Tuna Church is a medieval church located north-east of Uppsala. The church was probably built at the end of the 13th century, with the church porch and sacristy being later medieval extensions. The interior of the church was altered in the 15th century, when a vaulted ceiling replaced an earlier, wooden ceiling. The church was heavily renovated in the 1890s, when the medieval frescos were uncovered and insensitively restored. They were originally probably made by a local artist. The wooden belfry of the church was built in 1768.
The design of the church is typical for north-eastern Uppland, but the unusual use of brick rather than fieldstone as building material as well as the placement of the entrance at the western gable indicates influences from the type of architecture popular among mendicant orders.
The church still contains several medieval items: a couple of wooden sculptures of saints (including Bridget of Sweden), a decorated baptismal font and a paten of gilded copper. Other, post-Reformation furnishings include the pulpit (1674) and an richly decorated chasuble from 1662.
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.
