Llantilio Crossenny (Welsh: Llandeilo Gresynni) is a small village and much larger former community, now in the community of Whitecastle, in Monmouthshire, south east Wales, in the United Kingdom.

Hen Gwrt, (English:Old Court), Llantilio Crossenny, Monmouthshire is the site of a thirteenth century manor house and a sixteenth century hunting lodge. Originally constructed for the Bishops of Llandaff, it subsequently came into the possession of the Herberts of Raglan Castle. The bishops constructed a substantial manor house on the site in the thirteenth century, which was moated in the fourteenth. The building was then adapted by the Herberts to create a lodge within their extensive hunting grounds. The lodge continued in use until the slighting of Raglan Castle in the English Civil War. Historical accounts of Monmouthshire traditionally identify Hen Gwrt as the home of Dafydd Gam, the legendary opponent of Owain Glyndŵr and supporter of Henry V, but there is no evidence for this. Work at the site in the early nineteenth showed evidence of the footings of the earlier buildings, which were mapped, but by the time of subsequent archaeological investigations in the twentieth century, all of the stone on the site had been removed for road metalling. Today, no trace of either the manor or the lodge remains, and the moated site is in the care of CADW.

White Castle (Welsh: Castell Gwyn), also known historically as Llantilio Castle, is a ruined castle near the village of Llantilio Crossenny in Monmouthshire, Wales. The fortification was established by the Normans in the wake of the invasion of England in 1066, to protect the route from Wales to Hereford. Possibly commissioned by William fitz Osbern, the Earl of Hereford, it comprised three large earthworks with timber defences. In 1135, a major Welsh revolt took place and in response King Stephen brought together White Castle and its sister fortifications of Grosmont and Skenfrith to form a lordship known as the "Three Castles", which continued to play a role in defending the region from Welsh attack for several centuries. King John gave the castle to a powerful royal official, Hubert de Burgh, in 1201. Over the next few decades, it passed back and forth between several owners, as Hubert, the rival de Braose family, and the Crown took control of the property. During this period, White Castle was substantially rebuilt, with stone curtain walls, mural towers and gatehouses, forming what the historian Paul Remfry considers to be "a masterpiece of military engineering". In 1267 it was granted to Edmund, the Earl of Lancaster, and remained in the hands of the earldom, and later duchy, of Lancaster until 1825. Edward I's conquest of Wales in 1282 removed much of White Castle's military utility, and by the 16th century it had fallen into disuse and ruin. The castle was placed into the care of the state in 1922, and is now managed by Cadw, the Welsh heritage agency.
