The Rock of Cashel dates back to the 4th century, when it served as the seat of the Kings of Munster. It’s said that St. Patrick converted them to Christianity here in the 5th century. In 1101, the rock was donated to the church and transformed into an ecclesiastical center. Entry is granted through the 15th century castle and the Hall of the Vicars, which houses a museum exhibiting the original Cross of St. Patrick. At the top of the grassy hill, you’ll find the partly ruined 13th century Gothic cathedral and 12th century round tower. The highlight of the complex, however, is the 12th-century Cormac's Chapel, widely considered as one of the finest examples of Romanesque architecture in the country. While entry is only via guided tour, it’s well worth it to see the beautifully carved doorways and some of the oldest wall paintings in Ireland. Please note: as one of the most popular destinations in Ireland, the castle can get quite crowded. For more information, please visit www.cashel.ie
