- Tirdaglas Monastery
- Tír dá glass Monastery
Former monastery in Tir da glas, Ireland. Throughout its existence the house was known as a center of learning. The monks there produced the Book of Leinster c.1160, which is now housed in Trinity College Dublin; it is an important collection of history, tales and poems written in Middle Irish, and is believed to be the work of Áed Ua Crimthainn, a 12th century abbot of Terryglass. Vikings frequently raided the abbey, and it was burned in 1164; only a partial wall remains of the structures. There are two nearby healing wells, the Eye Well and the Headache Well.
