A key visitor attraction in North Tipperary, Redwood Castle is a striking example of a Gaelic tower house. It was home to the Ó Cinnéide (O'Kennedy) lords of Ormond and later on to the Mac Aodhagáin (MacEgan), Ireland's most famous family of hereditary brehon lawyers. Tours of the castle are available for school groups and they last approximately one hour and visitors must be well mobile to climb the steps of the spiral stairs.
