12thc C. – St. Mo-Diomog, Clonkeen, Co. Limerick
The monastery was founded by St Mo-Diomog, in the 6th-7thc. A small rectangular church with antae at E and W end. Roofless, but with walls fairly well preserved. The W part of the church incorporating the fine W doorway is Romanesque, built of roughly coursed large stones, mostly sandstone.
The capitals and columns with chevrons are similar to those at Aghadoe, Co. Kerry which has been dated to around 1158). Clonkeen probably dates to the mid 12th Century based on comparison with Aghadoe. The church was already in ruins in 1657.
