Cormac Chapel is considered the prime jewel of Cashel. It is decorated with Romanesque carvings throughout the building. The north portal tympanum shows a centaur on a hill pointing to a lion with an arrow. It dates back to 1127 and was probably the oldest Romanesque church in Ireland. Its stone roof is somewhat reminiscent of an inverted boat hull. According to locals, it is said that it houses the remains of King Cormac in the sarcophagus inside. You can still see remains of frescoes on the walls.
