Roch Castle was built by Norman knight Adam de Rupe in the second half of the 12th century, probably on the site of an earlier wooden structure. After the deRupe family died out in the 15th century, the Castle was taken over eventually in the 17th century by the Walter family. Their daughter Lucy was born in the castle, and later became a courtesan of Charles II, and bore him an acknowledged son James, 1st Duke of Monmouth.
During the English Civil War, the Walter family declared for King Charles I. Although Pembrokeshire was initially Royalist, the Puritans gained the upper hand. The castle changed hands twice, before the Walter family fled when it was captured for a second time by the Parliamentary forces and subsequently burned in 1644. It lay dormant and unclaimed until the return of Duke of Monmouth, who led a rebellion and was captured at the Battle of Sedgemoor, and then beheaded on 15 July 1685.
The castle remained decaying until 1900, when purchased by John Philipps, 1st Viscount St Davids, who restored it with a steel frame and new concrete floors to the designs of D. E. Thomas of Haverfordwest. Further works were carried out in 1910 and circa 1918–20, the latter by D. F. Ingleton.
The Castle was purchased in 2008 by Keith Griffiths for the Griffiths-Roch Foundation and was restored for operation by the Retreats Group as a six-bedroom luxury hotel Roch Castle Hotel.
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.
