The first written record of a church on the site of current Bladåker Church dates from 1316. The presently visible church, however, dates from the late 15th or early 16th century, with the exception of the sacristy (13th century) which is the only remains of the earlier, probably otherwise wooden, church. The church is constructed of fieldstone, with brick having been used for details and decorations in the façade. The external bell tower, made of wood, was erected in 1748. Inside, the church is decorated with frescos, dating from 1623. These were painted over during the 18th century but have since been restored. Among the church furnishings, a late medieval sculpture of the Holy Virgin and a number of wooden funeral coat of arms from the local nobility can be mentioned. The altarpiece is especially noteworthy as it was painted by Anna Maria Ehrenstrahl and donated by her to the church.
The church lies in a small hamlet, containing several well-preserved historical farmhouses and the former church school.
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.
