The Grote (Great) or Maria Magdalenakerk is a late-Gothic cruciform basilica replaced an earlier church built in the 12th century which probably stood at the location of the nave of the current church. In the 15th century, when Goes transformed from a village into a town, the church was extended to the east. Between 1455 and 1470 the choir was rebuilt. Originally a hall-choir seems to have been intended, consisting of three equally high and wide aisles. Instead a basilican choir was built, but with three almost equal apses closing each of the three aisles. The transept was completed in 1506.
In 1618 a fire destroyed much of the church. The nave was rebuilt in Gothic style between 1619 and 1621. This choice of style is a bit remarkable considering the fact that the church had been in protestant hands since 1578. An architect from Antwerpen, Marcus Antonius, designed the new five-aisled nave, resulting in a church in Brabantine Gothic style. Natural stone was used for the clerestorey while a combination of brick and natural stone was used for the side-aisles and facade. As traces in the western walls of the transept seem to show, the previous nave had probably been wider than the current one. In 1620 a steeple was placed on the crossing.
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.
