The sacristy and the northeast side of the Danderyd Church were built around 1400. The current appearance dates mainly from the restoration made in 1600s. The church has a strong relation to Baner noble family, who owned the church lands and the near Djursholm Castle for centuries. There are two grave of Baner family in the church and the pulpit (1628) and altar (1707) are donated by them. Among other inventory there are also a medieval Christ sculpture (1100s), curificix (early 1200s) and Madonna sculpture (1300s).
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.
