Located 26 kilometres south of the Diamond, the abbey consists of ruins which dominate the beautiful terrain. Situated where the River Eske meets the Donegal Bay, the monastery was founded in 1474 by the first Red Hugh O'Donnell and his wife Lady Nuala for Franciscan Friars.

For the next 130 years it became one of the most important centers for religion and learning till the beginning of 17th century when the abbey was abandoned with the intrusion of English reign. The friars remained active in secrecy for years to follow.

In 1632 the Irish historian and lay brother of the Order, Brother Micheal O Cleirigh (Michael O'Cleary) along with Cu Choigcriche O Cleirigh, Peregrinus O Duibhgeannainn and Fearfeasa O Maol Chonaire gathered all the records of Irish history. Together they came to be known as "The Four Masters". The abbey is named after them.
