The Chapelle de la Trinité is the first church in baroque style built in Lyon. It was created by the architect Étienne Martellange, a Jesuit brother who introduced architectural models of the Counter-Reformation in Lyon. Built between 1617 and 1622, the chapel is located within the building of the Grand Collège, under the direction of the Jesuits since 1567. It was devoted to college students. It was consecrated in 1622. The decor is very refined with coatings of Carrara marble.
Until September 1799, the chapel served as a barracks. In 1801, the First Consul was there proclaimed President of the Italian Republic. Thomas Blanchet, Horace le Blanc, Magnan and Pierre David are the sculptors or painters whose works can be seen in the chapel. There are often patrimonial visits, haute couture shows, seminars and charity work in the chapel. About 30,000 people visit it each year.
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.
