Tregrug Castle (Welsh: Castell Tregrug; Welsh pronunciation: [ˈkastɛɬ trɛˈɡriːɡ]) or Llangibby Castle is a ruin in Monmouthshire, Wales, located about 1 mile (1.5 km) to the north of the village of Llangybi, close to the settlement of Tregrug. The castle appears to have superseded an earlier Norman motte-and-bailey castle, which is first mentioned in records dating from 1262. Surrounded by dense woodland, on the top of a ridge, the present remains include a large, nearly rectangular walled enclosure, about 164 m (180 yards) by 78 m (85 yards), surrounded by ditches - the size of the bailey makes it the largest single-enclosure castle in England and Wales. The bailey is entered through a gatehouse, to the left of which stands a large stone tower, known as the 'Lord's Tower'. Recent archaeological thinking suggests that the castle's main function may have been recreational rather than defensive; it was probably built as a hunting lodge, with accompanying gardens in the style of a late medieval ‘pleasance’. The castle had fallen into disuse by the 16th century but was refortified and garrisoned during the English Civil War. Slighted at the war's end, it was subsequently redeveloped as a landscape garden feature, to complement a new house, New Llangibby Castle, which was built in the grounds at the very end of the 17th century.

Burrium was a legionary fortress in the Roman province of Britannia Superior or Roman Britain. Its remains today lie beneath the town of Usk in Monmouthshire, south east Wales. The Romans founded the 48 acres (19 ha) fortress around AD 55, probably for the Legio XX Valeria Victrix (20th Legion) and perhaps an additional ala of 500 cavalrymen. Earth and timber defences surrounded a number of legionary barracks. The fort was key to the conquest of the Silures, a tribe very resistant to the imposition of Roman rule in Roman Wales, but in AD 66, the legion was transferred to Viroconium Cornoviorum (at Wroxeter) and their base in Wales was largely abandoned. It was briefly replaced by a works depot for iron working. The surrounding vicus seems not to have developed into a small town, although it may have had an official mansio.
