Cross-slab in An Tsráid

1) The graveyard (DG080-013009-) here at Glencolumbkille Church of Ireland (National Monument number 139 along with associated sites) is said to occupy the site of an ancient ecclesiastical site founded by St. Colmcille. It has been said (Herity 1971, 14) that some traces of a circular enclosure (DG080-013003-) survives although no sign of these were noted during the survey. A modern church stands within the graveyard just N of the site of a church pulled down in 1828. The older church (DG080-013004-) is said to have been 52ft x 21ft with walls 3ft thick and 12ft to 14ft high. It is said to have had a vaulted, arched tower at the W end (DHS 691). (2) Just S of the present church is the modern entrance to a souterrain (DG080-013002-). This leads to a subcircular shaft 1.8m deep which changes into a rectangular shape .5m x .7m at the bottom. The N side of this has a soil face, the E and W sides are formed of drystone construction and the S side consists of a lintel-roofed doorway .92m x .52m which drops .38m in two steps to the floor of the central chamber. This central chamber is 5.6m E-W and 2.3m N-S and on average 1.6m high. The walls are partially corbelled giving a top width of 1.38m to 1.65m. This gap is closed by slabstones, at intervals. The intervals are closed by smaller slabs at right-angles to the principal stones. In the SE corner of the chamber a doorway 1.08m x .49m opens into an E chamber 6.15m E-W x .86m N-S with an average height of 1.04m. The S wall of this chamber is in a line with the S wall of the central chamber. There is only slight corbelling in the W chamber (top width .7m) and the gap is closed with flagstones. The 2nd roof slab from the W end is a re-used cross-slab (DG080-013005-). An incised circular depression surrounded by a circular groove attached to straight stem is all that is visible of the design. The stone is obscured on its S side. The E end of this chamber ends in a soil face. In the centre of the W wall of the central chamber, .42m above the central chamber floor, is a doorway .94m x .4m leading into the W chamber. This chamber is 8.7m E-W and 1.1m high. It widens to 1.3m at one point but is mainly c. 1m in width. The walls are of drystone construction without corbelling and it is roofed with flagstones. Gaps between these are filled with smaller slabs as in the central chamber. About halfway along the chamber three stones in H-formation support the roof and 2.35m W of this, a single stone supports the roof (both of these features may be modern). 1.35m from the present W end two stones at right angles to the walls of the chamber form a door .82m x .56m. From this door to the W end the roofstones are stepped upwards and there is considerable soil slip under them. This may indicate the original entrance. The base of the wall in all three chambers is formed from large thin slabs set upright. This site occupies the most prominent position on the floor of Glencolumbkille valley. It is situated on a small height surrounded by fair pasture land. The above description was derived from the 'Archaeological Survey of County Donegal.
