Fairy fort / earthen ringfort in Cnoc An Bhróigín Thiar

Internal diam. c. 29m NE-SW, c. 27m NW-SE Lisnahorna/Lios na hEornan: A univallate rath situated on a W facing slope overlooking the narrow valley of a tributary of the Milltown river. It is enclosed by an earthen bank and fosse and there is a souterrain and possible hut-site in the interior. The fosse is only barely perceptible along the S sector, but elsewhere it has been reused as a laneway and is up to 2m deep and c. 2.3m wide at base. This may not reflect its original dimensions as the lane, when it diverges from the rath, also lies well below the general level of the field. Fragments of drystone facing adhere to the outer flank of the fosse but this may relate to its later use. A discontinuous field fence runs along the outer, upper edge of the lane. The bank varies from 2 to 3m in height above the bottom of the fosse and is up to c. 2m high internally. There are slight traces of drystone facing at points along its inner flank. The inner flank is also stepped for most of its circumference. An earthen field bank may have been constructed on top of the bank, thus creating this stepped profile, but this is not certain. The entrance gap faces SE. It is c. 1m wide but has been disturbed by animal traffic. The fosse is only faintly discernible in this sector and it was not possible to trace a definite causeway. A low mound of stone collapse in the interior of the site may mark the site of a hut but there is too little evidence for definite interpretation. The mound is 6.8m long and no more than .4m high. The souterrain which lies in the N sector of the interior is now inaccessible, but 2 openings allow part of it to be viewed. The visible section is roughly Z-shaped in plan. The southernmost opening consists of an earth-cut well which appears to be the original entrance. A lintelled opening, .6m wide x .6m high, on the N side of the well, opens into a slightly wider space, now blocked by collapse after a distance of 1.5m. The W side-wall is of drystone construction and is curved in plan. A short passage extends ESE from this. It is c. 0.8m wide, 2m long and the walls are constructed mainly of large upright slabs with some drystone walling filling the interstices. The collapse at the N side of the 1st chamber or entrance lobby conceals a short passage which opens onto the E end of the S wall of a passage which extends WNW for at least 2.5m and which is .65m high and .5m wide.
