Above is the majestic sixteen arch Maesycwmmer to Hengoed Viaduct stretching across the Rhymney Valley that linked Pontypool to Swansea, via Aberdare and Neath. Built in 1857, this 260 metre structure was commissioned by the Newport, Abergavenney and Hereford Railway and designed by their engineer Charles Liddel. The rail line actually crossing the Viaduct closed in 1964 but today it forms part of the Celtic Trail, the network of cycle routes across South Wales. |
