NameImageLocationTypeDateNotesBallyloughan CastleBagenalstown Castle13th centuryA ruined castle located near Bagenalstown featuring one of the finest gatehouses in Ireland. The castle's architecture would suggest that the castle was built by a Norman lord c. 1300 and was likely abandoned in the 14th century. Near the end of the 16th century, the castle was occupied by the Kavanghs and then passed to the Bagenals, and then finally to the Bruens in the 19th century.Ballymoon CastleMuine Bheag Castle13th centuryA Norman castle, assumed by some to be unfinished, built by the Carew family, likely Roger Bigod, sometime between 1290 and 1310, possibly to defend the Barrow river valley from Irish raiders in a region over which the Normans had little control. In the past, the castle has been erroneously associated with the Knights Templar.Carlow CastleCarlow Castle1209A once mighty fortress erected by William Marshall upon the site of a motte-and-bailey built by Hugh de Lacy in 1180. The castle has seen combat in various hostilities: the Silken Thomas Rebellion, an attack by Rory Oge O'Moore in 1577, the Irish Rebellion of 1641, the Irish Confederate Wars, and the Conquest of Ireland by Oliver Cromwell. In 1813, the castle was leased to a Dr. Phillip Parry Price Middleton, who attempted to renovate it into a mental asylum in 1814. The castle was demolished after a partial collapse caused by an explosion and abandoned until 1996 when the castle was given into the care of the Office of Public Works.Huntington CastleClonegal Country house1625A castle constructed by the Esmonde family in 1625, after Queen Elizabeth I's forces captured the area and gave it to the Nettervilles, who then gave it to the Esmondes. A branch of the family, the Robertsons, still maintain ownership of the castle and it still serves as their ancestral home. Despite this, the castle is open to the public. In addition to a shrine to the Egyptian goddess Isis, the castle is noted as being haunted.Leighlinbridge Castle, or Black Castle of LeighlinbridgeLeighlinbridge Bawn118011811547A castle built by Hugh de Lacy in 1180 to defend the river crossing, rebuilt by John de Clahull in 1181, and once again rebuilt in 1547 by Edward Bellingham after its destruction in the 14th century by the Cavanaghs. The castle was sacked again by Cromwellian forces under Colonel Hewson in 1650 during the Irish Confederate Wars.Tinnahinch CastleCountry housec. 1620Tinnahinch Castle was built in the early 17th century by James Butler to control a bridge that once stood on this spot, but was confiscated from him for his involvement in the Rebellion of 1641. The castle burned down in 1700 and remains a ruin.
