Dolwyddelan Castle is located on a mountain pass in the
Vale of Conwy[?] in
North Wales[?]. It consists of two rectangular towers linked by an irregular curtain wall. It was built in the early
13th century, as one of the strongholds of the Welsh princes. It was captured by
Edward I's forces on
January 18,
1283. In the
15th century, an upper storey was added to the keep.
Dolwyddelan is believed to be the birthplace of Llywelyn ap Iorwerth.
