15 and 17, Castle Hill

15 and 17 Castle Hill is a pair of cottages, now serving as a folk museum and a house. Built in 1739, they were converted around 1820 into two cottages and restored around 1977. The structure is made of roughly coursed sandstone rubble with quoins and features a stone slate roof, topped with a gable chimney stack on the left. The building has a shallow double-depth plan, consisting of two low storeys and three bays that were originally symmetrical around three doorways. The central doorway led to the back yard, while the right-hand doorway has been recently altered into a window. The remaining paired doorways have chamfered surrounds and deep lintels, with the initials 'RTA' and the year '1739' inscribed above the central jamb. The first bay on the left features a square chamfered surround with a 19th-century sixteen-pane sashed window, similar to the former right-hand doorway. On the right, there is a large square 20-pane sashed window within a plain surround, showing marks of former shutter-lugs in the jambs. The first floor has three low rectangular windows, all fitted with 19th-century eight-pane sashes, but showing evidence of original chamfered flush mullions in the center. At the rear, just outside the current yard wall, there is a restored well protected by a circular wall. Inside the museum, there is a fireplace with shouldered jambs and a small cupboard in the staircase featuring a fielded panelled door with H-hinges.
