Before the St. Catherine's was built, a 14th-century Dominican church occupied the area. When the Jesuits arrived in Zagreb in the early 17th century, they thought the original church too rundown and inadequate, and worked to build a new church. Construction began in 1620 and was completed in 1632. A monastery was built adjacent to the church, but now the spot is home to the Klovićevi dvori art gallery.
St. Catherine's church was victim to fire twice in history: once in 1645 and again in 1674, devastating the interior. The church was refurnished with help from wealthy Croatian nobles, and in return, they were allowed to display their family coat-of-arms or have the honour to be buried or entombed in the church.
After the disestablishment of the Jesuits, St. Catherine's became part of the parish of St. Mark's in 1793. Since 1874, St. Catherine's has been a Collegiate church.
The church was severely damaged by the 1880 earthquake. After 6 months of repairs, it was reconsecrated in November 1881.
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.
