Mirepoix Cathedral (Cathédrale Saint-Maurice de Mirepoix) foundation stone was laid by Jean de Lévis on the 6th May 1298. Construction continued, with interruptions, over the next six centuries. The cathedral was restored in 1858 and 1859. The cathedral has the second widest Gothic arch in Europe (after Girona in Catalonia, Spain).
Inside the cathedral vandalism and demolitions has destroyed many treasures but you can still admire a tabernacle, a Christ on the cross from the 14th century and seven paintings by Larivière-Vesontius.
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.
