The Church of Our Lady of Liesse was built in 1740 on the site of a 17th-century church. The first stone of the Church of Our Lady of Liesse was laid down on 21 November 1620, in a ceremony attended by Grand Master Alof de Wignacourt and many other members of the Order of St. John. The church was built with funds donated by Fra Giacomo De Chess du Bellay, who was the Bailiff of Armenia.
The church was completely rebuilt by the Langue of France in 1740, and was blessed by Bartolomé Rull. The church was consecrated by Bishop Vincenzo Labini on 23 November 1806. The church was hit by German aerial bombardment in 1942 during World War II, but it was repaired and reopened on 21 February 1952. It was given to the Apostleship of the Sea on 15 September 1961.
The church is built in the Baroque style. It has a dome and a belfry which was designed by Francesco Zammit. It has three altars.
The titular painting of the church depicts a legend about three knights and Our Lady of Liesse, and it was painted by Enrico Arnaux. The relics of the martyr St. Generoso are stored in the church, and they were transferred there from the chapel of Fort Manoel. A statue of the Virgin Mary which had originally been located at Fort Saint Elmo is now found in a niche in 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.
