Man-made underground passage in Doire Mhór Thoir

Circular bivallate rath KE037-009---- is situated on level ground about 300m S of Tralee Bay. The entire monument is densely wooded and overgrown with briars and gorse, but an extensive Man-made underground passage and traces of hut-sites are visible in the interior. Souterrain (KE037-009002-): The exact lay-out and extent of the Man-made underground passage is also unclear but 2 separate sections are traceable. It is of drystone construction throughout and each chamber and passage is roofed by a series of flat slabs. The main section is roughly T-shaped in plan and consists of a small, rectangular chamber contained within the thickness of the inner bank at S, and 2 rectangular chambers extending S from this towards the centre of the enclosure. The chambers are linked by narrow creepways. (1) The northernmost chamber is 1.2m wide and at least 6m long N-S; its N end is completely blocked by collapse. A low, lintelled creepway leads from the base of the S wall to the N wall of chamber 2. It measures .55m in width, .38m in height and .55m in length. It is now partly blocked by loose stones and chamber 1 was not entered on this occasion. (2) This chamber is 1.2m wide and 4.2m long. The drystone-built side-walls are slightly corbelled and, at roof level, the chamber width is reduced to .85m. At present, access is provided by an opening in the roof where a roof slab has collapsed. Originally, however, it was entered from chamber 1 and the main entrance must lie further to S where the Man-made underground passage is no longer traceable. The S wall is provided with an alcove or recess which is .45m wide, 1m long and 1m high. Its single roofing-slab is set .2m above the level of those roofing the chamber and the floor of the alcove slopes gradually upwards towards the rear. A narrow creepway slopes upwards from the rear of the alcove to chamber 3 which is set at a higher level than chamber 2. The difference in height between the roof levels of the 2 chambers is 1m. The creepway is 1.2m long and c. 0.7m wide, but its original height is not known as earth fill has intruded from the chamber above. Its roofing slabs are stepped upwards from N to S and the final lintel lies c. 0.15m below the roof of chamber 3. (3) The creepway opens onto the N wall of this chamber, about .45m from its W end. The opening is .35m wide and .35m high. The chamber is 2.8m long E-W, .67m wide and c. 0.5m high. The E and W walls are partly obscured by collapse and the roof slabs above these have been removed. Another separate section of the Man-made underground passage is traceable in the W sector of the rath. It consists of a passage, at least 7m long, which runs E from the inner edge of the ringfort bank at W. This is not accessible but can be viewed where a couple of its roof slabs have collapsed or been removed. It measures .5m wide at the level of the roof and is a maximum of .75m high. Its E end is completely blocked and it is not known if or how it was linked to the remainder of the Man-made underground passage. A little beyond its W end, erosion of the bank has exposed 2 to 3 courses of drystone masonry which extend c. 2m in a NE-SW direction. This may be part of a further passage or chamber contained within the thickness of the bank. The above description is derived from J. Cuppage, ‘Corca Dhuibhne. Dingle Peninsula archaeological survey.
