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: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).
