A saint who left only a name
St Baire and the old church
The placename Cill Bhearaigh breaks into kil, church, and berry, from Baire, the saint the original church was dedicated to. Almost nothing is recorded about him, which is common enough with the early Irish saints attached to small rural foundations. What survives is the ruin itself: the often ivy-covered remains of the nave and tower of the medieval church, standing in the graveyard with a south doorway and a gate arch dividing the ground. You can look up inside the partial tower. It is a quiet, unvisited ruin of the kind south Kildare is full of, the church that gave the parish its name long outliving any memory of why.
A vanished medieval cluster
The abbey, the nunnery and Kilberry Castle
The farm beside the old church is still called Abbey Farm, after a religious house linked to the Hospitallers of St John that later became a nunnery and appeared on the 1837 Ordnance Survey map. It once stood next to the church and beside Kilberry Castle, whose remains were absorbed into the farm buildings, and the abbey ruins themselves are virtually gone. A field to the north held the stump of a second castle, Castlereedy, once the seat of the La Rede family. The land was long the home of the Verschoyles. Three or four layers of medieval and post-medieval history, most of it now reduced to a farm name and a fragment of wall.
A Norman tower on the river
Rheban Castle across the Barrow
Rheban Castle stands on the west bank of the River Barrow, around 5 km northwest of Athy and a short way west of Kilberry. A stone castle was raised here by Richard de St Michael, baron of Reban, in the reign of John as Lord of Ireland, after the Norman invasion. The name is thought to come from riogh, king, and bawn, an enclosure. The O Mores of Laois took it in 1325; it passed to the FitzGeralds by marriage in 1424, was raided for treasure by Sean O Broin of the Glenmalure O Byrnes, and changed hands repeatedly through the Confederate Wars of the 1640s before falling into the ruin it has been ever since. It gives its name to the local barony and to Rheban GAA.
