Ballynahow Castle, County Tipperary

The ground floor is lit with small slits located in the recesses of the wall, with the lighting giving it a cruciform appearance. It was used to keep animals, while the first floor served as a sleeping chamber. Three rooms are located in the second floor, which functioned as the primary living area; the larger room having a fire place, a toilet, and a smaller room for storing food. The third floor was also used for accommodation purposes, and the fourth floor was another living area with a fireplace. The noteworthy feature of this floor is the prison that can hold up to three individuals and a secret chamber set within thick walls and accessible from a hole in the north wall. The fifth floor was similar to an attic, and presently, a conical timber roof mounted on squinch arches covers it. All the rooms at the higher levels have one or two windows for lighting purposes.

This tower has walls that have splayed ends; its two lower chambers are quite small due to the thickness of the walls, while the three upper floors are larger. These three floors are rectangular in shape and have ogival and segmental headed windows. Only two ceilings, on the ground and third floors that were made of stone still exist, while the ones made of wood collapsed long ago. Amongst the two preserved ceilings, one is vaulted and the other is flat corbelled. A cottage and few out buildings are situated in the vicinity of the tower; however, the overall area has a very desolate look, even though the caretaker lets out accommodation nearby. As it is one of the very few round castles in Ireland, it has gained special significance as a heritage site and is highly regarded among historians.
