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:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
