from the Atlas van Loon map from 1905, the canals are all filled in The church was designed by the architect Peter Noorwits, assisted by the painter and architect
Bartholomeus van Bassen. It is considered a highlight of the early Protestant church architecture in the
Netherlands. Like many churches of the time, the New Church was designed as a central building. Unlike other central buildings, the church has no simple circular or multifaceted plan but there is a space of two octagonal sections connected by a slightly smaller section in which the pulpit was prepared. The
Dutch Baroque architecture of the church shows elements of both
Renaissance and
Classicism. Two church bells, cast by Coenraat Wegewaert in 1656, hang in their original bell-chairs and measure 100,2 cm and 81,5 cm in diameter. He also designed the clock. The church houses an organ built in 1702 by the Dutch organ builder
Johannes Duyschot (1645–1725), most of whose pipework and case survives. The organ was rebuilt in 1867 by one of the best organ builders of that time,
Christian Gottlieb Friedrich Witte. His company adjusted the design of the organ to make it suitable for modern
Romantic music. Until the canals in The Hague were filled in at the end of the 19th century, the New Church was accessed by boat or from the Wagenstraat on a square island between the Spui river, the St. Anthonisburgwal or Rotterdam Veerkade (the old
trekschuit route to Rotterdam), the Stille Veerkade or Amsterdam Veerkade (the old trekschuit route to Amsterdam), and the Paviljoensgracht. ==Concert hall==
