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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
