Dolbadarn Castle (Llanberis)
Dolbadarn Castle is a little known castle at Llanberis in North Wales.
It stands in wooded ground, on a rock 80 feet above the piece of land dividing the two lakes of Lyn Padarn and Llyn Peris, behind the Royal Victoria Hotel.
The circular tower dates from the 13th century and was built by Llewelyn the Great. His grandson Llewelyn ap Gruffydd held his brother captive here for nearly twenty years.
After Llewelyn`s death at Builth in 1282 Dolbadarn came into the hands of Edward I, and he used some of the timber for the building of the mighty Caernarfon Castle.
During the uprising of Owain Glyndwr, Lord Grey of Ruthin was imprisoned here.
Dolbadarn Castle is in the care of Cadw.
