So why "the Devils Bit"? It was named after a mountain in North Tipperary, Ireland. Legend has it that a small gap in the mountain is where the devil took a bite and spit out the rock. That spit-out piece became the Rock of Cashel, which was the traditional seat of the kings of Munster in Ireland for several hundred years; most of the buildings that remain on the site date from the 1100's and 1200's. According to legend, Cashel is also the site of the conversion of the King of Munster by St. Patrick in the 5th century.
