The San Giovanni degli Eremiti church dates back to the 6th century. After the establishment of the Norman domination of southern Italy, it was returned to the Christians by Roger II of Sicily who, around 1136, entrusted it to the Benedictine monks of Saint William of Vercelli.
The church was extensively modified during the following centuries. A restoration held around 1880 attempted to restore its original medieval appearance.
The church is notable for its brilliant red domes, which show clearly the persistence of Arab influences in Sicily at the time of its reconstruction in the 12th century, the Arab-Norman culture. However, the red colour of the domes are not original, as they were restored in the present way at the end of the nineteenth century by an architect who found pieces of red plaster on the domes and therefore decided to paint all the domes in red.
The church lies with a flank on a square construction. The church is on the Latin Cross plan with a nave and two aisles and three apses. Each of the square spans is surmounted by a dome. The presbytery, ending with a niche, has also a dome.
The cloister, enriched by a luxurious garden, is the best preserved part of the ancient monastery. It has notable small double columns with capitals decorated by vegetable motifs, which support ogival arches. It also includes an Arab cistern.
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.
