Raglan Castle is a late medieval castle located just north of the village of Raglan. 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.
Following the Norman invasion of Wales, the area around the village of Raglan was granted to William FitzOsbern, the Earl of Hereford. Some historians suspect that an early motte and bailey castle may have been built on the Raglan site during this period.
The current Raglan Castle was begun by Sir William ap Thomas. In 1432 William purchased the manor of Raglan, where he had already been staying as a tenant, and commenced a programme of building work that established the basic shape of the castle as seen today, although most of, with the exception of the South Gate and the Great Tower, was later built over.
During the English Civil War the castle was held on behalf of Charles I but was taken by Parliamentary forces in 1646. In the aftermath, the castle was slighted, or deliberately put beyond military use; after the restoration of Charles II, the Somersets declined to restore the castle.
Raglan Castle became first a source of local building materials, then a romantic ruin. It now attracts visitors as a modern tourist attraction.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
