The Nieuwe Kerk was built in 1649 after the Great Church had become too small. Construction was completed in 1656. The church was designed by the architect Peter Noorwits, who was assisted by the painter and architect Bartholomeus van Bassen. The church is considered a highlight of the early Protestant church architecture in the Netherlands. Like many churches of that time was the New Church, a central building. Unlike other central building, the church is no simple circular or multifaceted plan but there is a space of two octagonal sections which are connected by a slightly smaller proportion in which the pulpit was prepared. The architecture of the church shows elements of both Renaissance and Classicism. Two church bells by Coenraat Wegewaert in 1656 hang in their original bell-chairs.
The church has an organ built by the Dutch organ builder Johannes Duyschot (1645-1725) in 1702. The construction has left most of the pipework and the cupboard. The organ was rebuilt in 1867 by one of the best organ builders of that time, the business of Christian Gottlieb Friedrich Witte. They adjusted the design of the organ to make it suitable for modern Romantic music.
The Nieuwe Kerk contains the tombs of the brothers De Witt and of the philosopher Spinoza. Spinoza's tomb is in the churchyard.
References:The Royal Palace was built in the first half of the 19th century as the Norwegian residence of King Charles III, who also reigned as king of Sweden and otherwise resided there, and is the official residence of the present Norwegian monarch. The crown prince resides at Skaugum in Asker west of Oslo. The palace has 173 rooms.
Until the completion of the Royal Palace, Norwegian royalty resided in Paleet, the magnificent town house in Christiania that the wealthy merchant Bernt Anker bequeathed to the State in 1805 to be used as a royal residence. During the last years of the union with Denmark it was used by the viceroys of Norway, and in 1814 by the first king of independent Norway, Christian Frederick.
