Dolwyddelan Castle (Welsh: Castell Dolwyddelan) is a Welsh castle located near Dolwyddelan in Conwy County Borough in North Wales. It is thought to have been built in the early 13th century by Llywelyn the Great, Prince of Gwynedd and Wales. Initially comprising just one tower with two floors, a second tower was built in the late 13th century, and a third floor was added to the first during repairs in the late 15th century.
