Caerphilly is a county borough in south-east Wales that straddles the old boundary between Glamorgan and Monmouthshire, with Cardiff to the south-west and Newport to the south-east. Caerphilly is its main town, and the others include Risca, Ystrad Mynach, Newbridge, Blackwood, Bargoed, New Tredegar and Rhymney.
Gilbert de Clare began Caerphilly Castle in 1268, and its walls, towers, gatehouses and lakes cover about 30 acres; the south-east tower of the inner ward leans outward by about 10 degrees. Cadw looks after it, and the town is known for Caerphilly cheese. Coal shaped the valley to the north, which had forty pits by the start of the 20th century, all since closed. At the old Elliot Colliery the East Winding House survives, with a museum of the local coal industry on the site.
The broad Rhymney Valley forms the north of the county borough. The Rhymney River rises in the hills of the north and runs south for about thirty miles, turning east just north of Caerphilly before it reaches the Bristol Channel. The valley's spoil heaps have been cleared and the land landscaped, and Caerphilly Mountain stands between the town and the Cardiff suburbs of Lisvane and Rhiwbina.
