“The Four Altars”, Creggane, County Roscommon……referred to, at today’s Mass, by Father Peter.
During the Penal times priests risked their lives saying Mass in people’s houses, on the hills and behind fences. The Four Altars offered protection to the priest from the wind and rain while saying Mass. For example when the wind came from the north, the priest would say Mass at the alter facing south. From the beginning of the 18th Century places were named after the local Mass hill or Mass rock.
