Oriel Brondanw is housed in Plas Brondanw a 16th and 17th century small manor house in north Meirionnydd. It is the main house of the Brondanw Estate which Clough Williams-Ellis inherited, in rather a run down state, from his father, John Clough Williams-Ellis, in 1908.

Plas Brondanw is known not only as the home of the illustrious architect of Portmeirion but also for his creation of the captivating Grade I listed gardens. The house and gardens are now held in trust.

Oriel Brondanw, the artistic space within Plas Brondanw, is run by a separate foundation that promotes art as a means to celebrate the artistic life of Susan Williams-Ellis, the instigator of Portmeirion Pottery. She was the daughter of Clough Williams-Ellis and of the author Amabel Williams-Ellis, née Strachey. Plas Brondanw was Susan’s family home.

With its intimate rooms, human dimensions, access to natural light and borrowed landscape the Plas is a wonderful, idiosyncratic space for a gallery. Some of this may be attributed to the rebuilding of the 17th century wing after the calamitous fire of 1951, but also to the buttress rooms that Clough added to the old house in the 1930s as an elegant way of dealing with subsidence.
