Photogenic Landscapes and Historic Sites in Monmouthshire

Skirrid Fawr Chepstow Castle Llanthony Priory Grosmont Castle
Monmouthshire is one of the 13 ancient counties of Wales, and currently comprises about two thirds of its original size, after the 1974 transfer of the western section to five new, much smaller boroughs. The modern boundary of the county, or unitary authority, extends from Caldicot along a short section of the Bristol Channel, then follows the River Wye northwards, at one point incorporating a small area on the east side of the river, before moving northwest, past Monmouth to and a little beyond Llanthony in the Black Mountains, this the northernmost point. The western boundary of the country runs generally a short distance beyond the River Usk, coming close to Newport before veering southeast towards Caldicot and Chepstow.

Most of the land is rural, a mix of agricultural fields, small hills and winding valleys, with the most scenic areas being the Wye Valley in the east and the mountains of the far west. Monmouthshire contains a small section of the east side of Brecon Beacons National Park (most of which is in neighbouring Powys), including most of the Vale of Ewyas, and the isolated peak of Skirrd Fawr. Adjacent English counties are Gloucestershire to the east and Herefordshire to the north.

The landscapes are pretty, but Monmouthshire is perhaps best known for historic buildings, in particular its castles. Of the original 20 or so, nine are largely complete; four are found in city centres while the reminder have picturesque, rural settings. The relative abundance of castles is a consequence of the strategically important location, close to the historic boundary between Wales and England, which used to be a little further west of the current border; most of the forts were built by the English. The best castles are Chepstow, Raglan and White. Other noted antiquities include Caerwent Roman Town, which features extensive city walls up to 20 feet high, dating from the third century, and the beautiful monastic remains of Tintern Abbey and Llanthony Priory.
