The Monolithic Church of Saint-Emilion is an underground church dugged in the early 12th century of gigantic proportions (38 metres long and 12 metres high). At the heart of the city, the church reminds the religious activity of the city in the Middle Ages and intrigues by its unusual design. If it shows itself in the eyes of the visitor by the position of a 68-meter-high bell tower, then it hides itself behind the elegance of three openings on the front and a Gothic portal often closed.
The goal of its realization is probably the development of the city around a pilgrim activity on the tomb of the patron saint St. Emilion. In memory of the Breton hermit who had settled in a nearby cave during the 8th century, and in order to edify the faithful, the ambition to achieve a sufficiently large reliquary church to host hundreds of pilgrims, was born.
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.
