The Noorderkerk ('northern church') was built between 1620–1623 to serve the rapidly growing population of the new Jordaan neighbourhood. The Jordaan already had a church, the Westerkerk, but the city government decided that a second church should be built to serve the northern part of the neighbourhood. The Noorderkerk became the church for the common people, while the Westerkerk was used mainly by the middle and upper classes.
The architect was Hendrick de Keyser, who also designed the Zuiderkerk and Westerkerk, among others. After de Keyser's death in 1621, his son Pieter de Keyser took over and oversaw the completion.
While the Zuiderkerk and Westerkerk have a more traditional basilica design, the Noorderkerk has a symmetrical, cross-shaped layout, reflecting the ideals of the Renaissance and protestantism. De Keyser's unique design combines an octagonal floor plan with a structure shaped like a Greek cross, with four arms of equal length. Annex buildings occupy each corner of the cross, and a small tower sits in the centre of the cross. Large Tuscan pillars dominate the church interior. The bell tower was built in 1621 by J. Meurs.
The church is still used for Dutch Reformed Church services and is also used regularly for classical music concerts.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
