Eskelhem Church was preceded by a wooden church, of which nothing remains. Circa 1200 it was replaced by a stone church. The walls of the nave of the present church are all that remains of this edifice. The church was successively enlarged and rebuilt until it received its present form in the middle of the 14th century.
Internally, the church is decorated with different sets of frescos, dating from the end of the 13th century and the 15th, the latter by the Master of the Passion of Christ. Among the church furnishings, the baptismal font from the 12th century, probably made by Master Byzantios, and the triumphal cross, made around 1250 both deserve mention.
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.
