Castell Dolwyddelan is a thirteenth-century Welsh castle situated in the Conwy valley, Gwynedd, North Wales. Built during the reign of Llywelyn ap Iorwerth (Llywelyn the Great), the castle served as a stronghold controlling the upper Conwy valley and represents an important example of native Welsh medieval military architecture. The castle comprises two round towers connected by a curtain wall, positioned on a rocky outcrop that afforded strategic defensive advantages. The site retains substantial medieval masonry and has been subject to archaeological investigation and conservation by Cadw, the Welsh heritage monuments authority.
