On the way to Clogrennan Wood you will see this beautiful arch lovely setting beside the River Barrow – this is Clogrennane Castle. Located about two miles distant from Carlow town. And this is one of the National Monument of Ireland in County Carlow.
Clogrennane Castle was built by sometime in the 15th century in order to defend a pass that wound along between the River Barrow and the extensive woodlands that were all along the side of the hills. It is believed to be in ruins since the 18th century and in the 19th century it was converted into the entrance to the then newly built Clogrennane House. The ruins bare little resemblance to the original Castle and seem to incorporate stone from a near by ancient church.
Near the ivy-covered ruin of the old castle a tunnel has been discovered, said to connected Clogrennan with White’s Castle (the modern house on Graiguecullen Bridge is built on the site of this castle) and Carlow Castle.
