The Groote Kerk of St. James (15th and 16th centuries) has a fine vaulted interior, and contains some old stained glass, a carved wooden pulpit (1550), a large organ and interesting sepulchral monuments, and some escutcheons of the knights of the Golden Fleece, placed here after the chapter of 1456.
It is remarkable for its fine tower and chime of bells, and contains the cenotaph monument of Jacob van Wassenaer Obdam, designed by Cornelis Moninckx and sculpted by Bartholomeus Eggers in 1667, and the renaissance tomb of Gerrit van Assendelft (1487 - 1558).
The church's six-sided tower is one of the tallest in the Netherlands. There are 34 panels with shields and names of knights of the golden fleece. The mechanical clock has 15 bells by M. de Haze in 1686, one by Jasper and Jan Moer from 1541, one from H. Van Trier from 1570, one by Coenraat Wegewaert from 1647, and one from C. Fremy from 1692 and 31 modern bells. In the church tower there is an automatic carillon by Libertus van den Burgh, from 1689.
The church endured a fire in 1539, and the stained glass windows were repaired by leading glass artists, including the brothers Dirk and Wouter Crabeth of Gouda. Charles V, Holy Roman Emperor, who visited the church after the fire, sponsored two windows by the Crabeth's that due to their royal origin are the only two windows that have survived up to the present day. Under one of these windows lies a commemorative stone from 1857 for Constantijn and Christiaan Huygens, who were buried in unmarked graves in the choir of the church.
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.
