In the village of Cong, County Mayo, visitors can see the ruins of a 12th-century Augustinian abbey established by Turlough O’Connor, High King of Ireland. The land had previously housed a 6th-century church associated with St Feichin.

At one time, the abbey had 3,000 inhabitants, who were excellent scholars and skilled craftsmen. It is also the location where Rory O’Connor, Ireland’s last High King, died.
