The Cathedral of Arlesheim served as the main church of Arlesheim and the cathedral of the Diocese between 1679-1792. After the French Revolution, when the Prince Bishop Sigismund Roggenbach had to leave and go into exile in Constance, then he returned to Freiburg in 1793. The building and its contents were auctioned after serving successively as a wine cellar and a stable. It became a religious building again in 1812, and was later consecrated as a parish church of the parish of Arlesheim.
Arlesheim cathedral belongs to Switzerland’s first great Early Baroque church buildings. The foundation stone was laid in March 1680 and the building was consecrated in 1681. Canon houses were built and nobles, highranking clergy, diplomats, artists and craftsman all moved here. The cathedral with its famous Silbermann organ is not only under the Virgin Mary’s protection, but also under federal protection as a cultural monument.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.
