Cefn-coed Viaduct was built in 1866 and is 770 ft (235 m) long and 120 ft (36.6 m) high. It is a rusticated-limestone structure of fifteen arches, set on a curve. The tall, slender piers and parapets are constructed with coursed irregular sized rock-faced limestone blocks

The Cefn-coed Viaduct is the third-largest viaduct in Wales. This huge, curved structure once carried the Brecon and Merthyr Tydfil Junction Railway and is now part of the Taff Trail, which is Route 8 of the National Cycle Network that runs between Cardiff and Brecon. It offers walkers and cyclists a superb view of the Taf Fawr as it cascades over the many weirs in the valley

Not much left of the old iron works. With a bit of time, experience and phantasy you can roughly reconstruct the old site, but without knowing the history you could as well overlook these ruins.

Here is very little of what is left of the remains of the ironworks that put Merthyr on the map. Unable to access these now as fenced off but once was accessible

The Rocking Stone or "Y Maen Chwyf" in Welsh is a glacial boulder remaining from the Ice Age. It formed the central point for a "Gorsedd" or "Gathering of Bards" in 1814, which was organised by stonemason, Edward Williams, known as "Iolo Morganwg". The Gorsedd Circle of smaller stones was constructed in 1849 by Evan Davies, Bardic name "Myfyr Morganwg" and has often been used for Bardic gatherings, and as a focal point for other public occasions.
