“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.

Treowen, Wales

Four-storey Jacobean house built on a double-pile plan, perhaps the most important early C17th gentry house in the county. Particularly fine open well staircase. Used as a farmhouse from the 1670s to the 1990s and never remodelled; everything visitors see is the unaltered work of its age. Delightful gardens with breathtaking views and woodland walks.


Treowen offers the ideal setting for those who want to create their own special day, rather than accept a standard wedding package.

Treowen offers a range of reception rooms, as well as plenty of accommodation for guests. An extensive private garden with superb views gives the perfect setting for an outdoor reception. Treowen is licensed for civil weddings.

Use the Dining Room, the Banqueting Hall, the Oak Room, the Long Drawing Room or, for an "outdoor" wedding, the Porch.
