The oldest part of the Rute church is the choir, built c. 1230. The nave was built around ten years later, while the tower and the west portal were the last parts of the church to be built. The church was decorated with frescos inside during the late Middle Ages. These were executed by the artist known as the Master of the Passion of Christ and were rediscovered during a renovation in 1951.
The church ceiling is supported by square pillars, a solution not found in any other church on Gotland. Among the furnishings, several are medieval. The baptismal font dates from the mid-13th century, while the triumphal cross was made c. 1260. A decorated tombstone, carrying inscriptions with runes, was found during the 1951 renovation and dates from the 12th century. The altarpiece is made of sandstone and may originally have been placed in the church of Visborg Castle.
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.
