Skeppsholmskyrkan is a church on the islet of Skeppsholmen, secularized in 2002. Named after its location, the church was built 1823-1849 to replace a minor wooden church on Blasieholmen destroyed in the devastating fire of 1822. Inaugurated by King Charles XIV John and still officially carrying his name, it was designed by the architect Fredrik Blom as a neoclassical octahedral temple inspired by the Pantheon in Rome, borrowing the coffered ceiling while substituting the oculus for the temple-shaped lantern light. On all sides, the plain white walls restored in 1998 are pierced by portals whose four pillars support semi-circular lunettes. Inside the cruciform exterior, the interior sheet of the wooden double cupola is supported by paired doric columns and rounded arches. Accompanying the painted altarpiece are niches with statues of the apostles and two plaster groups.
The Skeppsholmen parish was discontinued in 1969 when the Navy moved to Muskö, and the church was secularized in 2002. Since May 2009, the building is called Eric Ericsonhallen, named after the Swedish conductor Eric Ericson and is a Concert Hall managed by the Eric Ericson International Choral Centre.
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.
