The Black castle is situated at Leighlinbridge, Co Carlow commanding a dominant position over the river Barrow. The Barrow was immensely important in medieval Leinster acting as both an important route way and a natural barrier.
The photo of the plaque below gives a brief history of the castle while the other pictures show the site from different angles.
Unfortunately the castle is not accessible. What you see in this post is as much as you can see at the site which is disappointing – its not really worth a visit. A far better castle on the Barrow is Ballyhack in Wexford which is completely accessible.
