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 Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
