The Gothic spires of St. Mary's Church reach upwards and towards the heavens, towering impressively in the background of the town hall. First mentioned in archival records dating to 1283, the church was later rebuilt as a three-aisled hall church, and is today considered to have one of the most impressive Brick Gothic interiors thanks to its vaults. Amongst the most impressive features in the church is a choir screen dating to the second half of the 15th century– behind the screen is an ornate, Late gothic goldleaf wood carved altar with two doors. The church also boasts a unique astronomic clock that's still in operation today.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.
