Cavan
In 1938, work began on the Cathedral of Saints Patrick and Felim, the main church of the Catholic Diocese of Kilmore. Five kilometres (3 mi) south-west of Cavan Town, on the R198, is the Church of Ireland Kilmore Cathedral, which contains a Romanesque doorway dating from the 12th century, reputed originally to have come from Trinity Abbey, located a short distance away upon Trinity Island in Lough Oughter. Most of the neo-Gothic Kilmore Cathedral was built in the late nineteenth century. A short distance from Kilmore Cathedral is the See House, a late Georgian-style house constructed in the 1830s. This house, designed by William Farrell, was formerly the official residence (or "Bishop's Palace") of the Church of Ireland Bishops of Kilmore, Elphin and Ardagh.
