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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
