After the Oude Kerk ('Old Church') grew too small for the expanding population of the town, the bishop of Utrecht in 1408 gave permission to build a second parish church in Amsterdam. The Nieuwe Kerk ('new church') was consecrated to St. Mary and St. Catharine.
The church was damaged by the city fires of 1421 and 1452 and burned down almost entirely in 1645, after which it was rebuilt in Gothic style. It underwent major renovation in 1892–1914, which added many neo-Gothic details, and was again renovated in 1959–1980. It was the renovation in the 70's that became too expensive for the Dutch Reformed Church, and when they said the church would be closed most of the time to save money on maintenance, it was decided to transfer ownership in 1979 to a newly formed cultural organization called the Nationale Stichting De Nieuwe Kerk.
The Nieuwe Kerk is no longer used for church services but is used as an exhibition space. It is also used for organ recitals. There is a café in one of the buildings attached to the church that has an entrance to the church (during opening hours). There is a museum store inside the entrance that sells postcards, books, and gifts having to do with the church and its exhibitions.
The Nieuwe Kerk is a burial site for Dutch naval heroes, including Admiral Michiel de Ruyter, Commodore Jan van Galen, and Jan van Speyk. The poet and playwright Joost van den Vondel is also buried in the church.
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.
