The survey of the archaeology of Eigg by the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) has identified and mapped over 1150 individual structures. Processing this body of data is currently underway and, once it is completed, detailed descriptions of all recorded archaeological sites will be available from the National Monuments Record of Scotland (accessible through Canmore). In the meantime, this interim account summarises and illustrates the more important aspects of the extensive and often spectacular archaeology of the island.
The islands are largely composed of igneous rocks formed during a period of intense volcanic activity beginning about 60 million years ago and lasting around three million years. In the northern half of Rum, however, Torridonian sandstones predominate, and small areas of Jurassic sandstones, mudstones and limestones are visible around parts of the coasts of Rum, Eigg and Muck. The three smaller islands are largely formed from a series of lava flows, chiefly of basalt and mugearite. These have weathered into gently sloping terraces bounded by vertical cliffs, and the rocks readily break down to provide a fertile soil. Towering above the southern end of Eigg, the Sgurr is a block of pitchstone - a cooled lava flow which has filled a river valley cut deeply into the basalt, and has now been left standing proud as the softer valley sides have eroded away. The igneous rocks on Rum have a different origin; these are mostly intrusive rocks that did not break the surface but cooled deep within an enormous volcano, now eroded down to its roots. Neither these rocks nor the hard-wearing sandstones of the northern half of the island have supplied the nutrients essential for the development of fertile soils; this factor, combined with Rum's high rainfall (about 300cm a year at Kinloch), has produced a landscape dominated by wet heathland, limiting settlement and cultivation to a few more favoured locations. |

Apart from the brief notices of 17th- and 18th-century travellers, the authors of the Statistical Accounts and the notes in the Ordnance Survey Name Books, the earliest account of the archaeology of any of the Small Isles is that by Norman MacPherson, proprietor of Eigg. His paper of 1878 on the antiquities of the island included a report of an excavation he initiated of the Viking graves at Kildonnan, as well as details of a number of earlier discoveries, mostly made during land improvement operations. The islands also came to the attention of several other late-Victorian scholars, particularly those attracted by the early medieval crosses on Eigg and Canna. The first attempt at a systematic survey of the islands, however, was the Royal Commission's visit in 1925. Fieldwork for the Inventory of The Outer Hebrides, Skye and The Small Isles (1928) began in 1914, but it was only at the tail end of the project, which had been disrupted by the war and financial stringencies, that the Small Isles were visited, all recording apparently being completed during a single week in early July 1925. Fifteen monuments or groups of monuments were recorded, most of them on Canna. On Rum only one site, Kilmory church and burial-ground, is described, while on Eigg only the fort on the Sgurr and Kildonnan churchyard appear to have been visited, both on the same day. For the next half century the islands attracted little archaeological attention. The Archaeology Division of the Ordnance Survey spent a month in the summer of 1972, principally to visit previously known sites, though several new monuments, including several hut-circles on Eigg and Canna, were mapped. A study of shielings on Rum by Ronald Miller in the 1960s, followed by John Love's more detailed work on the same topic, drew attention to the archaeological potential of that island, and in 1983 the Royal Commission returned to Rum and published a handlist of archaeological sites under the auspices of the Society of Antiquaries listing programme. The discovery of Mesolithic flints near Kinloch Castle in the course of that survey prompted a programme of high-profile excavations by Caroline Wickham-Jones in the following year. On Eigg, Peter and Susanna Wade-Martins, together with colleagues from Norfolk, completed surveys of a number of sites during the 1980s and 1990s, while in 1986 the Scottish Buildings Study Group at Dundee University surveyed farm buildings on both Eigg and Canna. However, it was not until 1994 that the Royal Commission returned to the Small Isles, embarking on a survey of Canna in partnership with the National Trust for Scotland. A broadsheet on the Canna survey was published in 1999, and a longer account has been incorporated into the fourth edition of the late John Lorne Campbell's Canna: The Story of a Hebridean Island. Further work on the Small Isles includes Muck, surveyed in 2002. Meanwhile, the Threatened Buildings Survey of the Architecture Division of the Royal Commission completed an in-depth photographic record of Kinloch Castle in 1996 and, in 1998-9, the principal buildings on Eigg were photographed and surveyed. Finally, all the early crosses on the islands were drawn for Early Medieval Sculpture in the West Highlands and Islands, published by the Royal Commission in 2001. Other archaeological organisations have also been involved in the islands in recent years. In 2001 Glasgow University Archaeological Research Division conducted an assessment of the archaeology of Rum for Scottish Natural Heritage. In the same year, stimulated by the Royal Commission survey, the National Museum began excavating a Late Bronze Age metalworking site on Eigg, while an assessment has been made of a wooden boat, possibly 18th century in date, buried in the sand in Galmisdale Bay. Finally, excavations in advance of new pier developments on Eigg and Rum have produced quantities of worked flint. |

The Bronze Age (2500-700BC) The vast majority of hut-circles in the Small Isles are on Eigg, where thirty have been mapped, and on Canna, where there are twelve. By contrast, only one has been identified on Muck and none of the few suggested examples on Rum are convincing. The visible remains comprise low, circular, stony banks, often faced with large edge-set stones, which would have supported a timber-framed conical roof. Nearly all of the Eigg and Canna examples are situated in heather moorland or other rough pasture, well above the limits of post-medieval cultivation; very few survive within the areas of improved ground. This distribution explains their absence from the other two islands, for there is very little unimproved or uncultivated ground on Muck, while on Rum locations suitable for settlement have presumably always been restricted to the same few niches around the coast, densely settled and heavily cultivated into the early 19th century. Exploratory excavations of a hut-circle at Galmisdale by the National Museums of Scotland in the spring of 2002 have produced Bronze Age pottery, though the tradition of building round-houses probably spans most or all of the last two millennia BC. Apart from fragmentary traces of field-banks on moorland in north-west Eigg, it is only on Canna that remains of prehistoric field-systems can be identified. At the west end of the island hut-circles are spaced out amongst a network of fields and enclosures defined by edge-set stones. It may be that a mixed agricultural economy can be detected here, with smaller fields defining plots of arable, while longer boundaries, disappearing into the moorland peat, may have divided up areas of pasture. One of the more remarkable discoveries to emerge during the survey of Eigg also dates from the Bronze Age. In May 2001 Royal Commission staff were shown a collection of metal-working debris discovered by the late Brigg Lancaster while digging a hole to bury his cat. The collection included moulds for Late Bronze Age socketed axes, a knife and a pointed tool, along with fragments of crucible. Finds of Bronze Age metalwork are relatively common in Scotland, but there are no more than a handful of sites with substantial evidence for metalworking. Alerted to the discovery, the National Museums of Scotland immediately began excavating the site, and work has continued into 2002. It is thought likely that this is the temporary workshop of a Late Bronze Age smith, possibly an itinerant craftsman. |

The Iron
Age (700BC- AD500) One final prehistoric site on Eigg remains to be described. It stands amongst a jumble of gigantic boulders beneath the cliffs on the north-east coast, in many respects the most remote corner of the island. Here, a substantial platform has been constructed, on top of which there are the remains of a thick-walled circular enclosure. Opening from the interior there is the entrance to a large boulder cave that runs westward beneath the enclosure wall. The main chamber of the cave measures about 7 metres in length and there are other, smaller, chambers opening off to either side and at the end. The cave entrance and the sides of the chamber have been modified by the insertion of rough walling, and a thick deposit of midden material covers the floor, including animal bones, shells and broken hammerstones, some of which have a concretion of crushed shell on their points. Thus far, the site is unusual, but not unique - at Usinish on the east coast of South Uist there is another round structure constructed around the entrance to a boulder cave. What makes the Eigg site stand out is its position within the landscape. The cliffs on this side of the island are characterised by horizontal banding of different lavas, but immediately above the site the these bands are broken by a dramatic eruption of vertical basalt columns, soaring to the top of the cliff. Standing in front of the round-house, the eye is immediately drawn upwards, and the view is framed by two enormous boulders, one to each side. The sense that this has been a 'special place' is inescapable. Moreover, it is difficult to argue the case for an ordinary defensive or domestic function for the site. It is evidently a secluded spot, hidden away in the scree, over 400m of difficult terrain separating it from the shore. There are easily accessible shieling-huts and fragments of enclosure walls on grassy terraces close by, but to reach the enclosure involves a tricky scramble and the use of all four limbs. We know next to nothing about Iron Age religious practices in western Scotland, but it is tempting to speculate that this may be some prehistoric 'eremitic' site. |

Eigg certainly, and Canna probably, were the sites of important monasteries in the early medieval period. No visible remains of these survive, though both islands have rich collections of early medieval sculpture. There are six cross-slabs on Eigg, dating from the 7th to the 9th centuries. One of them has been known since the 19th century, and one was discovered in 1987 in Kildonnan churchyard, the probable site of the early monastery. The other four, however, are first recorded in the early 1930s, when casts were presented to the National Museum of Antiquities of Scotland. Nothing is known about the circumstances of their discovery, though it is assumed that they also came from the churchyard. Most of the crosses are now on display in the porch of the Lodge, and one has been re-erected at Kildonnan. Apart from its crosses, Canna also has the remains of an unusual monastic enclosure on its remote south-west coast, known as Sgorr nam Ban-Naomha, which may have been a hermitage subordinate to the monastery at A' Chill, and the presence of the early church on the other two islands is attested by two cross-slabs from each, and also by the placename Papadil ('priests' valley') at the southern tip of Rum. In contrast to these overtly Christian sites and monuments, all products of the Dalriadic church, a cemetery of at least fifteen square cairns was discovered during the survey just above the beach at Laig on Eigg. These may be regarded as pagan, quite possibly Pictish, and serve as a reminder that this part of Scotland was very much a frontier between the two peoples in the mid first millennium AD. Square cairn cemeteries are found throughout the area of the Pictish kingdom, with particular concentrations around Inverness and on the east coast as far south as Fife. They are, however, comparatively rare in the Hebrides, and the Laig cemetery is the largest yet recorded on the west coast. |

Norse placenames are common on the Small Isles, as of course they are throughout the Hebrides, but the archaeological evidence for the period is limited to a small, albeit important, group of artefacts, chiefly from Eigg, and a possible house discovered during the Muck survey. The Laig boat stems and the Kildonnan sword are amongst the best known Viking artefacts from the Hebrides. The stems, which were discovered in the 19th century during the draining of a bog, measure about 1.9m in length, and one of them has been stepped and hollowed to accept the timber strakes of the hull. The sword was discovered about 1830, together with a whetstone and fragments of other artefacts, while levelling a 'hillock' to the north-east of Kildonnan farmsteading; only the hilt, of silvered bronze, has survived. Two other Viking burials, this time to the south-west of Kildonnan, each containing a sword and other artefacts, are recorded, at least one of them placed in a prehistoric cairn. Otherwise, the only Norse artefacts from the Small Isles are an ivory gaming piece discovered in a cave on the east coast of Rum and a ring-headed bronze pin found on Canna. The possible Norse house identified on Muck is situated on the N coast of the island. Bow-sided on plan, it measures 13.4m by up to 5.4m within thick stone footings and has an outshot 6.8m long at its north-west end. In plan, at least, this building is clearly different to those of the 18th- and 19th-century settlements on the island, although, given our patchy understanding of rural vernacular building styles in the Highlands before 1700, a late-medieval date is also possible. |

The medieval and post-medieval periods
(AD1200-1800) There are few visible remains on the islands that can confidently be ascribed to the medieval period. Eigg has the remains of a church, outside which there stands a cross shaft of 14th- or 15th-century date, and there is a possible medieval chapel in the burial-ground on Muck. The medieval parish church on Canna is not visible, though its wall footings were identified by excavation in 1994, and a chapel probably stood in the burial-ground at Kilmory on Rum. The only castle on the islands, Coroghon, on Canna, is probably of 17th-century date. Many of the numerous shieling-huts on the islands are likely to be medieval, but the most interesting monuments that have been tentatively assigned to this period are the deer traps on Rum. The best-preserved of these comprises a high-walled oval enclosure set at the foot of a hillside. The deer are thought to have been driven down through a gap cleared in the scree on the slopes above and funneled into the enclosure. |

Draft plan of the Upper Grulin township. Although the layout is characteristic of 18th century joint townships, most of the surviving buildings have stone-cored walls, similar to the buildings of the early 19th century croft houses on the island. The remains of a prehistoric dun stand on a knoll at the south-west edge of the township. | ||
|
The township and field-system at Five Pennies is illustrated here. The visible remains comprise the footings of about two dozen buildings, a corn-drying kiln and several small yards and enclosures at the edge of an extensive system of irregular fields. The buildings are all roughly rectangular and usually have rounded external corners. In one instance, close to the centre of the township, two buildings are joined along one side, an arrangement commonly found amongst blackhouses in the Western Isles, where byres and other ancillary buildings would often be added to one side of the main house, rather than at its end. The fields around the township are enclosed by substantial turf and stone dykes, within which fragments of rig cultivation can be traced. Their wide variation in size and their irregular form strongly suggest a gradual, piecemeal process of expansion and enclosure of arable land. Field-systems such as this are common on the west coast of Scotland - examples have been recorded by the Royal Commission at Achiltibuie, Wester Ross, and on Waternish, Skye. The Five Pennies field-system has survived largely because it lay outwith the Cleadale crofting settlement established immediately to the south in 1809, where intensive cultivation has left only fragments of the earlier enclosures. |

· Shielings Aside from the shieling-huts, the remote pastures of Eigg are strewn with about 200 pens, small enclosures, and roughly-built shelters. These are particularly numerous below the cliffs of Beinn Bhuidhe on the north and east coasts of the island. Many of these structures are probably the work of shepherds, and are no more than 100 or 200 years old. Others, though, may be medieval or earlier, and it has been noted above that some of the rock shelters may date from early prehistory. |

The 19th
and 20th centuries The kelp boom collapsed when the end of the Napoleonic Wars allowed the importation of cheaper sources of alkali from Spain. Faced with a rising population increasingly unable to pay their rents, proprietors' attitude towards emigration quickly changed. In 1826, about 300 people were cleared from Rum, which was converted into a farm for 8000 sheep, and 50 more followed in 1828, leaving only one indigenous family. In the same year 150 people emigrated from Muck. The population of Canna was greatly reduced after its sale by Clanranald in 1826, and in 1849 it was halved again. On Eigg, 140 people elected to emigrate in 1843 and, ten years later, Laig and Grulin (roughly the western half of the island) were let for sheep and the Grulin crofters were evicted. |

· Sheep farms and Victorian
sporting estates Rum, with the extravagant Kinloch Castle, perhaps the ultimate shooting lodge, is closely associated with the Victorian and Edwardian passion for sporting estates, but the 19th-century proprietors of Eigg were also concerned more with the sporting opportunities offered by the island, and were content to leave the running of the farms largely to their factors. Norman MacPherson, who inherited the island from his father in 1854, surrounded his house with woodland to encourage pheasants, while Robert Thomson, who bought the island in 1896, considered moving all the tenants to Muck in order to make room for deer. The present Lodge, built in 1926-7, is the fourth proprietor's house built on or near that site, intended, like its predecessors, as a holiday house and base for shooting. Designed by a Newcastle firm, Mauchlen and Weightman, the lodge originally had a flat roof, but this was replaced in 1935 with the existing hipped roof. |

Eigg has a rich variety of archaeological monuments, many of which contribute in a highly visible way to the spectacular landscapes of the island. While many of these monuments are of types familiar from other parts of Highland and Hebridean Scotland, others are more unusual, even unique - a reflection, no doubt, of the island's position on the western seaways, which has exposed it to a wide variety of influences throughout prehistoric and historical times. The Royal Commission survey was made possible by a grant from the Scottish Wildlife Trust, with funds provided by the Heritage Lottery Fund, and also by the enthusiastic co-operation of the Isle of Eigg Heritage Trust and the residents of the island. |
