Devil's Bridge / Pont ar Fynach

Devil's Bridge, also known as Pont ar Fynach, is a Grade II* listed structure featuring three superimposed bridges. The lowest bridge is made of rubble stone and has a narrow, obtusely pointed single arch with stone voussoirs, likely refaced in the 18th century, and a flat coping. Above this, the second bridge was constructed in 1753 and is also made of rubble stone, featuring a single segmental arch formed from large squared stones, with large stone voussoirs at the ends and a deep masonry section above.

In 1814, the original parapet was removed and replaced with a cast-iron parapet supported by cast-iron scrolled supports, which rest on crude stone corbels. These supports terminate in pierced roundels. The parapet consists of ten joined cast-iron panels on each side, some of which are missing on the upstream side. Each panel is pierced with four pointed arches and features four roundels above, which encircle a concave-sided lozenge.

Massive raking abutments flank the stone arch, rising from the rock below. These abutments were altered and enlarged to support the bridge built in 1901, which is situated just above the earlier structures. The 1901 bridge has a flat concrete roadway on steel corrugated decking, supported by two steel deep I-beams that are pierced for lightness, replacing the original iron or steel girders from 1901. The original railings from 1901 have been reset and consist of a simple lattice of flat iron strips, with stone piers at each end. A plaque on the rubble wall to the southwest reads: 'Adeiladwyd gan Cyngor Siriol Ceredigion 1901. Gorchwylwr R. Lloyd'.
