Ardee Castle

Ardee Castle also known as St. Leger's Castle, is a fortified medieval tower house in Ardee, County Louth in Ireland. Built in the 15th century, the castle was used as a prison during the 17th and 18th centuries and became Ardee's district courthouse until June 2006 when a specialised facility took its place. Ardee Castle is the largest fortified medieval Tower House in Ireland or Britain. The castle was originally built by Roger de Peppard in 1207, but not much is left from the original walls.
