The Holy Cross Church was built between 1734 and 1739 (the towers were built in between 1854 and 1856) in the location of the destroyed in 1545 monastery of the Dominicans - for the need of Jesuits which arrived to the town in 1677 (architect J. Frisch). The church has a single-aisle, with a number of side chapels and the tribunes. The ceiling stands out due to J.Kubena frescoes (1739-1745) presenting the glory of the Holy Cross, the missions of the Jesuit Order and figures of saints.
References:The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
