Twthill, Rhuddlan

Twthill (Welsh: Twtil) is a Norman motte-and-bailey castle located near Rhuddlan, Denbighshire in North Wales. The earth and timber castle was built during the Norman invasion of Wales in the late 11th century. It was superseded by the much larger, stone-built Rhuddlan Castle which was built 200 years later during the Conquest of Wales by Edward I in the late 13th century. The historic names for the site include Toothill or Tot Hill; it is been referred to as Old Rhuddlan Castle. The only remaining parts are the large mound of the motte, and traces of the wall that surrounded the bailey.
