Pont Glantanat Uchaf

A single-arch bridge about 6 m wide in local uncoursed slate masonry with sandstone voussoirs and string course. The arch spans about 20 m and is of slightly rusticated voussoirs about 500 mm deep, and there are keystones each side. The intrados surface is similarly rusticated.

The parapets are about 1 m high in uncoursed similar slate masonry, and turn out slightly at all four ends. Flat copings including (downstream) most of a stone carved with a cross within a circle; also (upstream) the other remnant of this stone plus another with a more complete cross and circle. When the Commissioners examined these stones in 1911 they searched for accompanying inscriptions but found none.
