The abbey grounds contain not only the main church building and altar but also what local tradition identifies as the Abbot’s House, a rectangular structure situated just north of the abbey ruins. This building, measuring 12.2 metres by 2.6 metres internally, now appears as little more than grass-covered stone foundations, though its walls still retain enough form to hint at its original purpose.

The Abbot’s House has taken on a second life in local religious practice, with small cairns of stones dotting its interior; these were created by pilgrims performing stations, a form of devotional prayer common in Irish Catholic tradition. A modern tombstone has been incorporated into the eastern wall, suggesting the site’s continued significance to the local community. While the building’s identification as the abbot’s residence comes from oral tradition rather than archaeological certainty, its proximity to the abbey and its substantial construction support this interpretation.

The entire complex sits within its unusual five-sided graveyard boundary, a geometric oddity that sets it apart from the typical circular or rectangular enclosures found at most Irish ecclesiastical sites. This distinctive shape, combined with the survival of multiple structures and the site’s ongoing use for religious observances, makes Templedouglas a particularly intriguing example of how medieval monastic sites continue to serve their communities centuries after their original abandonment.
