Dating from 1684, this octagonal baptismal font was already an antique when the chapel itself was constructed in 1852. Standing just over a metre tall at 1.05 metres, it represents a fascinating example of late 17th-century ecclesiastical craftsmanship that has survived through centuries of Irish history.

The font’s construction showcases the skilled stonework of its era, with both the basin and base carved from white limestone and decorated with symmetrical moulding. The octagonal shaft, crafted from grey slate, provides an elegant contrast to the pale limestone above and below. This combination of materials and the careful attention to geometric form reflects the architectural sensibilities of the period, when such fonts served as centrepieces for baptismal ceremonies in parish churches across Ireland.

Originally documented in the Archaeological Survey of County Donegal, this font offers a tangible connection to the religious life of late 17th-century Donegal. Its relocation to the later chapel of ease suggests it was valued enough to be preserved and repurposed when its original church fell out of use. Today, it stands as one of the older surviving ecclesiastical artefacts in the area, its weathered surfaces bearing witness to over three centuries of christenings, changes in religious practice, and the evolution of the local community around Doe Castle.
