Pontygwaith Bridge is a historic, Grade II-listed stone humpback bridge that spans the River Taff near Edwardsville and Treharris, south of Merthyr Tydfil, Wales. Revered for its striking architecture and its setting within the Pontygwaith Nature Reserve, the bridge stands as a prominent icon of the region's industrial heritage. 1. History and Origins Ancient Crossings: Records indicate a river crossing has existed at this precise location as far back as the 1540s. The Ironworks Connection: A wooden bridge originally stood here to carry worker traffic across the river to a small ironworks established in 1583 by Sussex ironmaster Anthony Morley. The current name, Pontygwaith, literally translates to "Bridge of the Ironworks". The 1811 Stone Build: The wooden structure was replaced in 1811 by the beautiful, durable masonry structure seen today. 2. Architectural Features According to the official Cadw Listed Buildings Report, the bridge is registered as a structure of "exceptional character" due to its distinct construction: The Arch: It features a single stone arch built with a remarkably steep rise of 4.8 metres and a wide 16.8-metre span. Materials: It was meticulously assembled using local Pennant Sandstone rubble and thin, long cut stone voussoirs across the arch ring. Restoration: The main arch was heavily repaired and reconstructed by the Mid Glamorgan County Council in 1993, earning it a prestigious commendation from the Civic Trust for historical preservation. 3. Pop Culture & The Taff Trail Today Today, the bridge serves as a major focal point along the Taff Trail (National Cycle Network Route 8). It is a highly popular stopping point for cyclists and hikers to set up a picnic or take photographs. The bridge also gained television fame when it was used as a filming location for the BBC fantasy series Merlin. It served as the exact backdrop for the "Beauty and the Beast" episode, where a character has a secret picnic with a troll directly beneath the stone archway.

A remnant of Merthyr's past. This bridge carried a railway line that either took you through a tunnel to Aberdare or sent you north towards Cefn Coed and on to Brecon via Torpantau. Under the bridge was the Merthyr to Cardiff Glamorganshire canal which carried the produce of Cyfarthfa iron works to the ports of Cardiff which was then shipped all over the world.

This is a nice stone bridge along the cyclepath just outside Merthyr Tydfil which makes a pretty spot to stop and take a picture.

Absolutely loved the Taff Trail and it's contrasting scenery, starting in the mountains and Reservoirs of the Brecon Beacons through the working towns of the valleys and into the urban streets of Cardiff City. Fantastic contrast of landscapes industrial past and present. This trail is a must visit if you are in the area.
