Description

Y Sgwar, also known as The Square Restaurant, is a 2-storey building that serves as both a restaurant and a house. It is constructed from roughly coursed and squared blocks of quarried stone and features a slate roof with projecting eaves, hipped to the left, along with a skylight and a stone ridge stack. The building has two similar replacement shop fronts on the right, which include glazed doors and small-pane windows, all situated beneath painted fascias in earlier openings. At the right end, there is a replacement panel door. On the upper storey, there are two 6-pane hornless sash windows.
