Title: Clonmacnois Monastary Location: Leinster shore of the Shannon River, County Offaly, Ireland Founded by St. Ciaran in 545 AD, the Book of the Dun Cow was written by monks here around 1100 and the last high king of Ireland, Rory O'Connor was buried here in 1198. I may have named my son after him as I knew of him and always loved the name Rory (the Red King).   Available in Mat Sizes: 11x14 or order a 16x20   Email us to order this print.
