Some news on the The Black Lion, 11 Castle St, from the Council for British Archaeology:
"The former Black Lion pub (Y Llew Du) is a striking building in the medieval town of Conwy. It was thought to have been built in 1589 by the vicar of Conwy, John Brickdall. Converted into a public house in the 1700s, it was a venue for the Monday morning pig market and then used for other commercial activities in the 20th century. It has stood empty since the 1990s. A recent archaeological survey commissioned by the owner suggests the building may perhaps be of 15th century date.
Proposals to turn the building back into a single domestic dwelling have not been opposed by the CBA, but we objected to the removal of historic fabric by the proposed addition of three ensuite bathrooms and the removal of internal walls. The case also raised concerns over the public accessibility of the archaeological report, which the owner is presently not willing to make available, a position that the CBA considers to be deplorable."
