The graveyard measures 35 metres by 21 metres and is entered through stone steps on the northern wall, though recent conservation work has revealed evidence of burials extending beyond the enclosure into the field to the southwest. The memorials within are mostly 18th and 19th century headstones, with many of the early 19th century examples fashioned from repurposed Bangor blue roofing slates from north Wales, possibly salvaged from the church’s own collapsed roof or from other local buildings. These thin slate headstones have become particularly fragile over time.

The church forms part of an old turas, or pilgrimage route, dedicated to St Chróine, the patron saint of Templecrone. Every 7th of July, on the saint’s feast day, pilgrims would visit a series of sacred sites beginning with two holy wells to the west of the church. The first, Tobercrone, lies 150 metres from the church and consists of a narrow opening in the rock, though it has long since run dry. Further west, some 220 metres from Tobercrone, sits a second well called Toberfinan. The pilgrimage would conclude at a turas station 34 metres from the graveyard wall, where dedicatory offerings are still left today.

Just 20 metres west of the church and graveyard, grass covered wall footings mark the remains of what appears to be another rectangular building, though its date and purpose remain unknown. This clustering of religious structures; church, graveyard, holy wells, and pilgrimage stations; creates a sacred landscape that has drawn visitors and worshippers to this corner of Donegal for centuries, preserving ancient traditions of devotion in the Irish countryside.
