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.
