The oldest part of the existing St. Pierre du Bois Church was probably built around 1375. The rest of the church dates from the 14th and 15th centuries. The church sits in beautiful surroundings on a hillside. Its floor makes this all the more apparent as it slopes one and a half metres from east to west. When refurbished in the Victorian era, men and women sat separately and even entered through different doors. The church boasts an impressive tower containing 13 bells, the largest peal in the island.
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.
