A Step Back Through History

Cwmdu Glen has a fascinating historical background that connects deeply with the industrial heritage of the Swansea Valley. During the 19th century, Pontardawe and the surrounding areas were thriving hubs for coal mining and metalworking. The steep, wooded valleys like Cwmdu Glen were shaped not only by natural forces but also by the human hands of the Industrial Revolution.

Remnants of this industrial past can still be seen today. Walk along the trails and you may spot old stone structures, forgotten tramroads, and even traces of historic mining activities hidden beneath the trees. These woodlands once echoed with the sounds of industry; now, they offer peaceful walks where nature has reclaimed the land.

Glan-rhyd Plantation, meanwhile, reflects a later period of managed woodland planting. Today, a mix of ancient woodland and newer plantings make for a diverse and thriving habitat, rich in both native species and historical layers.

The Plantation was once in the grounds of Glanrhyd House which was a mansion house built by local industrialist Arthur Gilbertson in 1877. After Arthur's death in 1912 the house was requisitioned by the military and went on to become an auxiliary military hospital which would care for an treat wounded soldiers. A few years after the war ended the house was converted in to flats and was in use until 1965 before it later fell into sever decline and went on to be demolished. The house and gardens with its swimming pool, walled garden, plantation, tennis courts and stables were reflective of the grand style of the era and despite the mansion house being demolished in 1968, the walled garden, giant redwood, ponds and pool are still visible in the woodland today.
