St Gwenog's Church is a medieval building dating back to the late fourteenth century and is situated in the hamlet of Llanwenog.
This is a medieval church, and the only one dedicated to Saint Gwenog. It dates to the late fourteenth and fifteenth centuries, with the fine tower being added some time after 1485. It bears a plaque with the arms of Rhys ap Thomas, Lord of Dinefwr and Carew. The interior has the original fifteenth-century barrel roof. The pews and other church furnishings are elaborately carved. Some of the work was done by and to the design of Colonel Herbert Davies-Evans of Highmead at the beginning of the nineteenth century, and others by the celebrated Belgian wood-carver, Joseph Reubens of Bruges during the period 1914 to 1919.
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.
