Giske Church was built of white marble in the 12th century. The origin of the marble is unclear, but it was brought to the island by boat. Where it came from before that is unknown. Today the walls are covered by chalk on the outside and plaster on the inside, so that the marble is only visible in a few places, all on the outside. The architectural style is Norman.
The church was originally a family chapel consisting of the nave and chancel, but it has been refurbished several times over the centuries. The most extensive renovation was carried out in the 1750s (initiated by Hans Strøm), and most of the interior today can be dated back to this renovation, carved by the local craftsman Jakob Sørensøn Giskegaard (1734-1827).
The church is open for guided tours during the summer season.
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.
