Description
This listing describes a long flight of steps that lead up the hillside on the east side of Bull Street, flanked by rubble walls topped with flat stone slab coping. The central dividing wall is made of coursed blockwork and features a shaped, raking coping with a rounded central ridge and square newels at the corners, which have stepped and pyramidal caps. The steps themselves are constructed from large blocks of stone, likely sourced from a nearby quarry at Gelli Grin.
On the left side of the steps, there is a flat-headed archway that provides access to the grounds of Penlan. This archway is built from roughly coursed masonry and includes a slate slab drip course and coping that leads to an embattled parapet. The left flight of steps leads up to the main house at Penlan, while the right flight ascends to the servant's quarters, now known as Bryn or Penlan flats. The quality of the stonework and the width of the steps indicate the different statuses of their users, with the left flight being of significantly finer construction.
