The Rock of Cashel is also known as St. Patrick's Rock. The buildings date from the 12th and 13th centuries. St Patrick is said to have converted the King of Munster on this site in the 5th century. It is here he reputedly used a shamrock to explain the trinity to the king. Cashel includes a round tower, a 13th century Gothic cathedral and the 12th-century chapel. The Romanesque splendor of Cormac’s Chapel is seen in the detail of the doorway arches, the ribbed barrel vault, and the carved vignettes. Fragments of the once splendid frescoes survive.

St. Patrick's Cross is uniquely built in the Latin Style with two pillars running parallel with the main body of the cross, with supports at either side. One face depicts Christ's crucifixion, while the other shows the image of an abbot or bishop, perhaps St Patrick himself. Like anything associated with St Patrick this cross is associated with many legends, myths, and traditions and is said to have healing powers. A swift marriage is assured to those who perform a ritual involving hopping around the cross on one leg.
