The court tomb at Creggandevesky is located on the edge of the Sperrin mountain range (Grid ref. H64597503). The immediate environs of the site is mostly upland pasture and blanket bog. Before excavation the monument was recognisable as a long cairn aligned north-west to south-east, but was obscured by bog around its perimeter, and grass and heather over its top. There had been no previous excavations at the site. The Historic Monuments and Buildings Branch, Department of the Environment Northern Ireland purchased the land on which the site stood in 1984 and the monument is now in State Care. 1.2 Objectives 1.2.1 The excavation was prompted because the landowner (Mr. McCartan) wanted to remove the cairn and level the hill to fill an adjacent sand quarry and create more pasture. The initial excavation objective, therefore, was to excavate and remove the cairn and investigate any pre-cairn activity. As the excavation progressed and the well-preserved court tomb was uncovered the owner decided not to continue with the reclamation scheme. Consequently, the excavation objectives changed. It was decided that the area around the site would still be excavated to try and ascertain if there was any pre-monument activity. The excavation of the court area and the burial gallery would continue, but the cairn and revetment would be left intact as it was no longer necessary to remove the monument. 1.3 Excavation 1.3.1 A rectangular area 26.00m by 19.00m was laid out around the visible cairn material, with the long axis aligned north-east to south-west. This area was divided into quadrants. As the court tomb was exposed it became clear that the quadrants imposed on the site were not the best way to excavate the interior of the cairn. For recording purposes, therefore, the tomb was divided into the court area and the burial chambers I, II and III. 1.3.2 The court tomb was trapezoidal in shape and measured 13.50m across the south- east end of the monument, tapering to 6.80m at the north-west end. Extensive deposits of collapsed cairn material obscured the outline of the monument before excavation. When this was removed, the cairn was seen to be revetted for its full 1 Creggandevesky Court Tomb, Tyrone 1979 – 1982 CAF DSR 045 _____________________________________________________________________________________________ extent by stone walling. The back of the tomb measured 6.80m wide, and was largely defined by a single course of stone. Two flat facades at the ends of the ‘horns’ enclosing the court area were also revetted. The court area was at the widest, south-east end of the cairn. It measured 6.00m wide along the front between the two south-west facing facades, and was 5.00m deep. The arms were defined by two sets of spaced orthostats interspersed with panels of dry-stone walling. The entrance to the burial gallery was made of two portal stones supporting a lintel. The burial gallery was 9.50m long and was divided into three chambers by two pairs of jambs. 1.3.3 There were six phases of activity associated with the monument: Definite pre-cairn activity, possible pre-cairn/construction activity, construction activity, construction and burial activity, burial and abandonment and modern deposits. Individual deposits and features could not always be closely phased within the stratigraphic sequence. 1.3.4 Phase 1: Definite pre-cairn activity Definite pre-cairn activity was represented by a small trench cut into the sand and gravel sub-soil (context F75) and a square-cut feature to the east of this. These features were covered by a mixed soil deposit (context L13/27/28) into which was cut a shallow pit projecting from under the south-west facade of the cairn (context F68). 1.3.5 Phase 2: Possible pre-cairn/construction activity This phase consisted of a series of features and post holes cut into the mixed soil deposit in the court area (context L13/27/28), the sand and gravel sub-soil in chambers I and II (context L21 and L19), and a dark orange silt (context L23) and grey streaked soil (context L18) in chamber III. There were few inter-relationships between these cut features and deposits, and it was not possible to stratigraphically relate them to the construction of the court tomb. Consequently it is uncertain whether they pre- or post-date the construction of the cairn. 1.3.6 Phase 3: Construction activity The orthostats and associated sockets, including the sockets for the two robbed orthostats from chamber III (contexts F21 and F22), represent phase 3, the construction of the tomb. The monument was probably constructed by first setting the orthostats for the burial gallery and court area in the correct position. The cairn was then built up around these orthostats. The sockets associated with orthostats in the court area were cut into the mixed soil deposit that covered the court area (context L13/27/28). The sockets in chamber I were cut into the sand and gravel sub- soil (context L21) while in chamber III they were cut into dark orange stony silt (context L23). There was no evidence that suggested the court tomb had been significantly altered after its initial construction. There was some evidence for 2 Creggandevesky Court Tomb, Tyrone 1979 – 1982 CAF DSR 045 _____________________________________________________________________________________________ secondary activity, such as the removal of the back orthostats in chamber III, the possible repositioning of the corner stone (context O1) in the court area, and the deposition of burials into the collapsed cairn material. 1.3.7 Phase 4: Construction and burial activity This was the construction and usage phase of the monument. This was represented by a bright yellow clay (context L17) redeposited from the digging of two sockets at the rear of chamber III (contexts F21 and F22) from which several grave goods were found. 1.3.8 Phase 5: Burial and abandonment This phase was represented by the surface of the sand and gravel sub-soil (context L21) in chambers I and II and the surface of a bright yellow clay (context L17) in chamber III, which were contemporary with the burial phase of the monument. The collapse of the monument was also included in phase 5. The collapsed roof of sandstone slabs in the chambers and the accumulation of soils around them lay directly on the surface of the sand and gravel sub-soil (context L21). Grey sandy soil accumulated in the court area (context L14) above a yellow sandy soil (context L13) onto which the collapsed cairn material had accumulated. Although it cannot be proved from the stratigraphical record, it is a reasonable assumption to make that the cairn would not have collapsed in one event, but would have been a series of events spread over a period of time. Cremated bone and other artefacts found in the collapsed cairn material suggests a period of secondary burial use before the complete abandonment of the monument.
