Carreg Cennen Castle is erected sometime after 1284 by Baron John Giffard and his son on the site of an earlier Welsh fortification. In 1462, Carreg Cennen flies the Lancastrian flag. Taken on behalf of the Yorkist king Edward IV, it is slighted by pick and crowbar, ending its life as a stronghold. Carreg Cennen castle is spectacularly located on a great limestone crag about 90m above the river Cennen, offering views miles around.

January 24, 2024, Herbert's Quarry

Herbert’s Quarry is part of the Black Mountain and Mynydd Myddfai Registered Landscape of Outstanding Historic Interest in Wales. Unlike in other lime producing areas where canals and tramroads could be built, the industry at Herbert’s Quarry was served solely by road transport. The lime trade was a factor in the development of Turnpike roads, and the network of tracks and roads over the mountain is closely associated with the activity at Herbert’s Quarry. As you walk through the site you are taking a journey through time, and walking in the footsteps of many hundreds and thousands of people before you, people whose hard work, sweat and drudgery shaped this landscape and left a rich industrial legacy.
