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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
