Oxwich Castle occupies a position on a wooded headland overlooking Oxwich Bay on the Gower Peninsula, Wales. Although it may occupy the site of an earlier fortification, it is a castle in name only as it is a grand Tudor fortified manor house built in courtyard style.
A charter of 1306 granted in Swansea refers to tenants of 'the ancient knight's fees' (that is, military tenants) at Oxwich, and this indicates that there may have been some fortifications on the site before the present castle. At this time Oxwich was owned by the de Penres family, who had been in possession since the 1230s. However, with the exception of a ruined tower to the north-east of the castle, which may predate the Tudor building, (and may be the castrum de Oxenwych mentioned in a document of 1459) nothing remains of any earlier works.
The existing buildings were largely created in the 16th century. They consist of a Gateway (built 1520–1538) leading to a courtyard, a Hall at the east of the courtyard opposite the Gateway (1559–1580) and a South Range (1520–38). At the corner of the Hall and the South Range is the six-story South-East Tower. To the north-east of the Castle are the remains of a large stone dovecote.
The Gateway is surmounted by a plaque with the coats of arms of the Mansell family and the Penrice and Scurlage families to which Sir Rhys was related. The East Range carried a large Hall, and, with the South-East Tower to which it was connected, provided extensive accommodation. It is possible that the construction of this range may have led to the bankruptcy of its builder, Sir Edward Mansell. The South Range contained a kitchen.
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.
