St. Mochta's House is a medieval oratory and National Monument in County Louth, Ireland.

[3] Mochta (d. AD 535/543) was a disciple of Saint Patrick and established a monastery at Louth village c. 528.

In the year 1242, according to the Annals of Connacht, "The Archbishop of Armagh and the canons abbots of Ireland held a great chapter to honour the Order in Louth when some of the relics which Mochta had assembled from Rome were raised.

"[5] This suggests that Mochta brought back relics of other saints from Rome, but it's also possible that his own bones were added to them.

[7][8] St. Mochta's House is a rectangular building with barrel-vaulted roof, and a chamber above reachable by an internal stair.
