Liath Mor

Liath Mór is the site of a monastery founded by Saint Mochmaomhóg about 590. Two churches and a circular enclosure remain. The monastery continued until 1015 when the Annals record the death of the last abbot.
     

 
     
Liath Mór's Older Church
The smaller older building is of a typical early Irish style, with steeply-gabled walls enclosing a relatively small chamber. The church's antae (the projection of the side-walls beyond the gable walls) can be seen here. This is a distinctive feature of buildings of this type.
The foundation of a round-tower remains and earth-works indicate the various occupations of the site.
Built in the Irish Romanesque style, the larger, later building was renovated in the thirteenth and fifteenth century
 
The piscina was used for the cleansing of the altar vessels after mass. This example from Liath.Mór has a credence shelf above a shallow basin.
More elaborate examples are found in Hore in Holycross Abbeys.
