Heritage Open Day: A medieval manor house interior, with a rare and well preserved Norman undercroft and a 15th century roof, all encased in brick during the 17th and 18th centuries. In 1274, both passed by marriage to another notable family, the Somervilles. In about 1323, Joan Somerville married Rhys ap Gruffud. Their descendant Sir Walter Griffith is credited with restoring the Old Hall and adding its present roof in the 15th century.
The adjacent new Hall (not in the care of English Heritage, but open to the public) was built by Sir Henry Griffith between 1601 and 1610, probably to designs by Robert Smythson. In 1654, the estate passed to Sir Henry’s nephew, Sir Francis Boynton, and it remains in the ownership of the Boynton family.
