The Brecon Beacons National Park was the tenth National Park to be declared, in 1957. Indeed, three decades were to pass before there was an addition to the list, when the Broad's Authority, in effect another National Park Body, was confirmed in 1989. Embracing some 1,351km2 in the counties of Brecknock, Carmarthen and Gwent, the Brecon Beacons National Park extends in a broad band for almost 50 miles from west to east.
