The San Giovanni in Fiore Abbey date back to Joachim da Fiore's trip to La Sila in Calabria in 1188. Archaeological excavations have shown the presence of Joachim's first edifice, which was finished in 1198, in the Iure Vetere locality. The construction of the abbey was approved by Queen Constance of Hauteville after a Joachim's visit in her court at Palermo.
After Joachim's death in 1202, the first monastery and its annexed edifices were burned by a fire in 1214. The monks decided to abandon the location of Iure Vetere, also due to its difficult climatic situation.
In 1215 a site not far from the previous one was chosen, near the Neto river valley. The new abbey was completed in 1230, in the Romanesque style. In later centuries features were remodeled in different styles, including a Baroque style church interior.
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.
