There are numerous Bermingham monuments in Ireland, particularly in counties Kildare, Offaly, Galway, and Dublin. Most are now in a poor state but Athenry Castle in Galway has been restored, using building techniques similar to those employed when it was originally built.
There are a total of five castles and one monastery still in existence in counties Kildare and Offaly. Carbury Castle, Grange Castle and Carrick Castles are in County Kildare, while Blundell Castle, Kinnefad Castle, and Monasterois Monastery are in County Offaly. In Galway there is Athenry Castle and Monastery, Dunmore Castle and Bermingham House, the seat of the last Baron of Athenry and Earl of Louth, Thomas Bermingham, until his death in 1799.
