What makes them worth pausing over is not their scale but their contents: both mounds incorporate a considerable quantity of quartz, a material that appears repeatedly at early medieval Irish religious sites, where it seems to have carried some ceremonial or symbolic weight. The western mound is further defined by a single course of stone facing along its outer edge and by two cross-inscribed stones marking its western limit. These are leachts, a type of votive or commemorative cairn associated with early Irish Christianity, typically used as focal points for prayer or as memorials to a founder saint.

The enclosure in which they stand is known as Templenacloonagh, or Teampall na Cluanach in Irish, and it occupies a gently sloping west-north-westerly hillside at Leataoibh Mór in County Kerry. The site looks out clearly in most directions, with a particularly open view north-west towards Smerwick Harbour on the Dingle Peninsula's Atlantic coast. Inside the roughly sub-rectangular boundary wall, the remains of at least two buildings can be made out: one identified as an oratory, a small rectangular structure typical of early Irish monastic foundations, and a second that may have been a church. Two possible hut sites suggest the enclosure once accommodated a small community. The western mound of the two leachts measures 5.5 metres north to south and 2.5 metres east to west, rising to about 0.6 metres; the eastern mound is slightly broader at 3.5 metres east to west and similar in length and height. The site was surveyed and described by J. Cuppage in the 1986 Dingle Peninsula archaeological survey published by Oidhreacht Chorca Dhuibhne.
