Quick Summary

The Rock of Cashel is a prominent limestone outcrop in County Tipperary, Ireland, standing 358 feet tall. This site is crowned with a complex of ruins, including remnants of the town's defenses, St. Patrick's Cathedral, Cormac's Chapel, the bishop's castle, and an ancient cross.1

Historically, the rock served as the stronghold for the kings of Munster from the 4th century. Saint Patrick visited around 450 CE, baptizing King Aenghus and establishing Cashel as a bishopric. In 1101, the rock was gifted to the church. Cormac's Chapel was constructed between 1127 and 1134, and the cathedral was founded in 1169, with the current structure dating to the 13th century.1
