Oystermouth Castleis a familiar site in Swansea. It was rescued in the middle of the 19th century by local antiquary George Grant Francis, who employed workmen at his own expense to clear out the rubble and restore the walls, including a painstaking reconstruction of the chapel window from fragments of fallen tracery. It is thanks to him that we still have the building to enjoy.
This project has since concluded, but its original website has been archived to support ongoing interest and research. You can view the archived page here.
