If there is a castle that comes close to matching Harlech in historical importance, that castle is surely Chepstow. Chepstow is a Norman castle perched high above the banks of the river Wye in southeast Wales. Construction began at Chepstow in 1067, less than a year after William the Conqueror was crowned King of England.

While Edward had his master castle builder in the person of James of St. George, the Conqueror, some 200 years earlier, had his equal in the person of his loyal Norman lord William FitzOsbern. FitzOsbern's fortresses were the vehicles from which the new king consolidated control of his newly conquered lands. Chepstow Castle became the key launching point for expeditions into Wales, expeditions that eventually subdued the rebellious population.

Chepstow's Great Hall, begun in 1067, is the oldest surviving stone fortification in Britain. Because of this, the site has a special significance to British history. At other castles built during the Conqueror's reign, original Norman structures have long since disappeared, but at Chepstow it's still possible to see and touch the remains of FitzOsbern's first great building project in Wales.

The Normans weren't the first to recognize the strategic position of Chepstow. The arch above the main doorway to the hall is made from brick brought from a Roman fort that once stood nearby. The hall was always the heart of the castle, and originally stood alone. Over the years, the castle was enlarged by a series of builders. Today, the castle takes the shape of a long rectangle perched high above the river Wye.

Inside the hall, powerful men mapped out strategy with other Welsh "Marcher Lords," planning invasions to wrest control of Wales from groups of powerful princes still holding most of the country. Besides William FitzOsbern, earl of Hereford, Chepstow's other famous lords include William Marshal, earl of Pembroke, and Roger Bigod, earl of Norfolk. Depending on your perspective, these are some of the most important (or hated) men of Norman-Welsh history.

The Great Hall and dramatic cliff-side at Chepstow are the castle's two most interesting features. The rest of the castle is a typical Norman structure - a large gatehouse with high curtain walls connecting a series of tall towers. Because Chepstow was built in stages along the river Wye, the castle is constructed in a long, terraced fashion as opposed to a concentric layout. This unique construction is another reason the castle is so memorable.
