One of the surviving pillars (the one you can see from the A470) of the Walnut Tree Viaduct, reflected in the River Taff.
Built in 1901, the Walnut Tree Viaduct (so-called because it crossed the Taff Vale Railway above Walnut Tree Junction, at the southern end of modern-day Taffs Well) carried the Barry Railway 120 feet in the air across the Taff Gap from the Lesser Garth to the other side. What a view it must have been from up there, and certainly what a sight it was until it was dismantled in 1969.
