[citation needed] The monks had moved to Abbeymahon by 1278, when Diarmait MacCarthaig, son of Domnall Cairbrech, was buried in the ‘new monastery’.

The new site is on the estuary of the Argideen River, just over a mile east south-east of Timoleague, on the road to Courtmacsherry.

[6] Though it was thought in the 19th century that the abbey of Sancto Mauro / De Fonte Vivo was not the same as the ruins present in Abbeymahon, this is not the case.

[7] The abbots of Abbeymahon were rebuked several times in the thirteenth century for not attending the General Chapter when summoned.

[citation needed] It is likely that the abbey was protected by James de Barry, the 4th Viscount Buttevant, as it was not dissolved until some point between 1570 and 1587.
