Killoughternane Church is a 10th-century Celtic Christian church located in County Carlow, Ireland. It was built on the remains of a timber church said to have been built by Fortiarnán (Fortchern, Fortcheirn) in the 5th century AD.

Location

Killoughternane Church is located in southern County Carlow, northwest of Mount Leinster and about 6 km northeast of Borris.

The building

The church is made of local hammer-dressed granite, with walls 80 cm (2⅔ ft) thick. A baptismal font is in one corner, and there are antae on either side.^[1][2] Archaeological work showed evidence of a Neolithic burial ground.^[3]

St. Fortcheirn's Well

A holy well and altar stand across the road. Formerly pilgrims came from County Wexford across the Blackstairs Mountains seeking miraculous cures. In the 19th century a chalice (called the Braganza Chalice) and paten, both of silver inlaid with gold, were found hidden in the well. The chalice bore an inscription dating to 1595 and is believed to have been hidden during the Penal era when Irish Catholicism was repressed.^[4] Both are held at the parochial house in Muine Bheag.^[5]
