Wern Ddu Claypits is a Site of Special Scientific Interest near Van in Caerphilly County Borough, South Wales. The woodland is known locally as Coed y Werin, which surrounds a 19th-century clay pit, dug to supply clay to the Caerphilly Brick Company. It is designated because of the important coal measure rocks exposed there.
Geography[edit]
The Wern Ddu Claypits are located to the west of Caerphilly Town centre.[1] The site is measures around six hectares (15 acres).[2] The site is owned by the Caerphilly Woodland Trust and Natural Resources Wales.
History[edit]
The quarry at Wern Ddu is believed to be around 150 years old.[3] The area was the site of an opencast clay pit and a drift mine that provided material for brickmaking.[1][4] In the 1920s and 1930s the site was worked by the Black Vein Colliery and later the Caerphilly Brick Company.[5]
Production at the Claypits ceased in the 1960s and the area became largely derelict in the ensuing decades.[1] The site was designated a Site of Special Scientific Interest on 29 October 1984,[2] mainly due to large deposits of carboniferous and westphalian geology which are estimated to be up to 300-million years old.[1] Caerphilly County Borough Council describes the area as "one of the most important sites for helping understand the Westphalian geological history of the southern province of Britain."[2]
At the start of the 21st century, The Caerphilly Woodlands Trust took possession of the Claypits site and began developing the area.[1] In 2007, the Countryside Council for Wales carried out an extensive clear up process to develop the site for visitors.[3]
