Open Doors - Llwyn Celyn

At the southern end of the beautiful Llanthony Valley in the Black Mountains stands Llwyn Celyn. It was built in 1420 on the lands of Llanthony Priory and is a very rare survival. 

Llwyn Celyn is rich in medieval features and has barely changed since around 1690. It has been carefully conserved and restored by the Landmark Trust, and the building will be open in association with Cadw Open Doors.
