Raglan Castle
late medieval castle in Monmouthshire, Wales

Raglan Castle (Welsh: Castell Rhaglan) is a late medieval castle located just north of the village of Raglan in the county of Monmouthshire in south east Wales. The modern castle dates from between the 15th and early 17th centuries, when the successive ruling families of the Herberts and the Somersets created a luxurious, fortified castle, complete with a large hexagonal keep, known as the Great Tower or the Yellow Tower of Gwent. Surrounded by parkland, water gardens and terraces, the castle was considered by contemporaries to be the equal of any other in England or Wales.
During the First English Civil War, Raglan was occupied by a Royalist garrison on behalf of Charles I but was taken by Parliamentarian forces in 1646 and its walls slighted, or deliberately put beyond military use. After the Stuart Restoration in 1660, the Somersets declined to restore it and it became first a source of local building materials, then a romantic ruin. It is now a tourist attraction.
History
Early history of the castle
Following the Norman invasion of Wales, the area around the village of Raglan was granted to William FitzOsbern, the Earl of Hereford. Some historians, such as John Kenyon, suspect that an early motte and bailey castle may have been built on the Raglan site during this period: the location had strategic importance and archaeologists have discovered the remains of a possible bailey ditch on the site. The local manor was held by the Bloet family from the late 12th century until the late 14th century, and the family built a manor house somewhere on the site during this period, surrounded by a park. By the late medieval period the Raglan site was surrounded by the large deer parks of Home Park and Red Deer Park, the latter being enclosed at the end of the period.
