The Saint-Bonaventure church's history is intimately related to the convent of the Cordeliers whose it was a part. It was built originally in the 13th century. The current church was built in just two years between 1325 and 1327. It housed the remains of Jacques de Grolée, died on 4 May 1327, which is under the high altar, before being moved somewhere near the epistle in 1599. The church was consecrated on 18 September 1328 by the archbishop of Lyon, Pierre IV of Savoy, under the name of St. Francis of Assisi. The church was expanded from 1471 to 1484 and was then named Saint-Bonaventure.
The choir was restored in 1607. It served as a granary grain after the French Revolution before being used to worship in 1806 to getting its current facade under the Cardinal Joseph Fesch's leadership.
Around 1890, the church was cleared of the curia and buildings bordering it on its side, which allowed the expansion of the rue Grolée on its western flank.
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.
