Dolwyddelan, a mountain stronghold of the Welsh Princes, stands in a magnificent location deep in Snowdonia. It was built between about 1210 and 1240 by Llywelyn the Great, ruler of Snowdonia, to control a strategic pass through his mountainous kingdom. The core of the castle, the rectangular stone tower, was restored in Victorian times. It can be seen from miles around, standing proud on a ridge against the rugged backdrop of Moel Siabod. An inspiring setting with great views.
