Description
Talgarth Bridge is a road bridge that likely dates back to the late medieval period, when the river crossing was protected by Tower House. It features a segmental arch made of red sandstone rubble, which is not laid radially, and has a width of approximately 3 meters. The bridge carries a slightly hog-backed carriageway. The northern side was first widened by about 1.5 meters, using rubble that consists of more regularly shaped narrow stone slabs laid radially. In the 20th century, the southern side was further widened to create a pedestrian path. The parapet masonry slightly overhangs the arch stonework and has a flat coping. There is a vertical break on the western side of the north face, beyond which the masonry is battered and darker below, supporting the road at the same level. The southern parapet, which has been partially rebuilt, extends to the southeast corner of Tower House and curves back towards the entrance of Bridge House.
