Place & story

The stone roof of Saint Mochta's House

Saint Mochta's House probably dates from the second half of the twelfth century. Its stone roof makes it a distinctive survivor beside the ruined church of Saint Mary's Augustinian Priory, whose visible fabric belongs to the medieval period. Extensive restoration was undertaken in 1934. The small building's traditional name connects it with the early saint, but the structure itself was built many centuries after his lifetime. The pairing of an enclosed, roofed oratory with the larger open ruins preserves two very different medieval buildings within the same religious landscape. [2]

A monastery of scholars

The monastery at Louth was associated with Mochta, traditionally a British disciple of Patrick. John Healy's account brings together annalistic references to its scholars and repeated damage during the medieval centuries. Among the named figures is Molassius, a lector whose death was recorded in 1047. The settlement suffered destruction again in 1148, but the monastery was rebuilt and continued until the general suppression of religious houses. These references reveal a community whose educational and religious work persisted through several cycles of attack, loss and reconstruction. [3]

Folklore & tradition

A stream that followed the saint

In the traditions retold by Healy, a stream followed Mochta from his earlier monastery at Kilmore to the meadows of Louth, where he established his cell. Another story explains why Patrick did not choose Louth for his own principal church. An angel directed him north to Armagh, declaring that Louth was reserved for a pilgrim from Britain. Patrick later visited Mochta, and the two agreed that the survivor would care for the other's community. These saintly stories connect water, place and personal friendship with the remembered relationship between Louth and Armagh. [3]
