Hengoed Viaduct, Grade II* listed railway viaduct in Gelligaer, Wales
The Hengoed Viaduct stretches 284 yards across the Rhymney Valley, featuring 16 stone arches with spans of 40 feet each on a slight curve.
Charles Liddell designed this engineering structure in 1853 for the Newport, Abergavenny and Hereford Railway, completing construction in 1854 at a cost of £20,000.
The viaduct represents Victorian railway engineering excellence through its stone construction, standing 120 feet above the Rhymney River in South Wales.
Now part of National Cycle Route 47, the viaduct provides cyclists and pedestrians a crossing point between Maesycwmmer and Hengoed communities.
Each of the viaduct's piers tapers from 10 feet wide at the base to 5 feet 6 inches at the arch springing level.
