Ballymoon Castle is an Irish rune castle, located 3 km east of Muine Bheag in County Carlow. Magnificent and imposing, it is said to have been built in the 13th century for Roger Bigot, a wealthy bourgeois of the time.
Ballymoon Castle once consisted of a square courtyard, protected by impressive surrounding walls, several metres thick and about ten metres high.
A system of harrows still remains, once used to protect access to the building.
Nowadays, only the courtyard and these walls can be identified: the castle itself has been completely razed to the ground and only its foundations remain.
It offers a magnificent view of the surroundings and has the authentic charm of Irish ruins. Its access is free, and offers a rather nice visit!
