Treowen Manor

Book Tickets Online


“A Noble Mansion. It occupies a commanding situation from whence are surveyed some of the most interesting scenes in Monmouthshire.

Over the entrance is a stone square with the armorial bearings of nine different noblemen and other characters of high rank in this County.

A correspondent dignity pervades the whole of the interior. A staircase two yards wide, of 72 steps, with balustrades, the newels on the quarterspaces two feet round, the whole in solid oak, which still remains perfect, stands unrivalled in the Kingdom.” - Charles Heath 1787

Antiquarian Charles Heath's glowing description of Grade I listed Treowen remains as true today as when it was written.

Panelled rooms, magnificent staircases, delightful gardens, breathtaking views, private woodland walks and a lofty position at the far end of a half mile long drive Wales offer atmosphere, privacy and a very different adventure holiday for the discerning visitor.
