Mainistir Bhuithe – “ monastery of Buithe” is the 5th century monastic site founded by St Buithe. The site includes the remains of two churches built in the 14th century and a Round Tower from the 10th century, but it is most famous for its Celtic High Crosses. The round tower is about 28 metres tall, and is in very good condition. It was likely built shortly after 968 and damaged in a fire in 1098. The three high crosses date from the 10th century and form part of the scriptural group (showing biblical scenes). The 5.5-metre Muiredach's High Cross is regarded as the finest high cross in the whole of Ireland. It features Biblical Carvings from the Old and New Testaments of the Bible. It is named after an abbot, Muiredach mac Domhnaill, who died in 923.
