The present St Cadoc Church was built in the 13th century and is believed to have replaced an earlier church within the manor of Landimore. Restoration was carried out on two occasions in the 19th century and again in 1934. The font may have been salvaged from the earlier church which was abandoned because of the encroaching sea.
The church has a saddleback roof with a defensive intent. The interior of the church contained medieval wall paintings, including scriptural quotations and vine-leaf patterns, but these were destroyed during the Victorian era. Eighteenth-century maps show the church in its present location, near a mill, which went out of use in the 19th century, and 'Great House', which was demolished at a similar date.
In the 1840s, Rev W. L. Collins had the original pews removed, and installed a new window, which was itself replaced during the restoration of the mid-1870s.
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.
