Clondahorky Old Church, described in 1622 as ‘newly re-edified and well repaired’, served its community until 1752 when a new church was built at Ballymore. The early 17th-century structure, measuring 17.25m by 5.6m internally, is built of rubble with small pinnings and remarkably intact walls. Both gables retain their coping, with the western one crowned by a simple bellcote. The church features several blocked-up segment-headed windows; one in the east gable and two each in the north and south walls, all originally fitted with timber frames. The doorway at the west end of the south wall once had a timber lintel, now missing, with a segment-headed rear arch. Inside, sections of plaster still cling to the interior walls, whilst exposed masonry on the north wall and southwest corner shows evidence of fire damage.

The second church site at Kill has attracted archaeological attention due to nearby development proposals. In 1994, archaeologists conducted pre-development testing when a new dwelling was planned northwest of the church and graveyard. Eight trial trenches were excavated using mechanical diggers, revealing the natural stratigraphy of the area; thin layers of topsoil overlaying boulder clay and bedrock, but no archaeological remains, deposits or artefacts. The trenches ranged from 12.6m to 34m in length, strategically placed around the proposed dwelling site, septic tank area and access road. A second phase of testing in 2006, conducted when another dwelling was proposed approximately 60m northwest of the monument, similarly yielded no significant archaeological findings, though a stone ridge running along the western edge of the site was noted, likely formed from field clearance when an adjacent north-south pathway was created.

These churches represent the quiet persistence of faith in rural Donegal, where communities maintained their places of worship through centuries of political and religious upheaval. The Archaeological Survey of County Donegal has documented these sites as part of the county’s rich field antiquities, spanning from the Mesolithic period to the 17th century. Whilst the archaeological investigations around Kill church revealed little in terms of buried remains, the standing ruins themselves serve as tangible links to Ireland’s medieval past, their blocked windows and fire-damaged walls bearing witness to the cycles of use, abandonment and the occasional violence that marked these sacred spaces.
