Château de Cambiaire was built in the 14th century in the town of Saint-Étienne-Vallée-Française. It is a quadrangular building with a round tower at three of its corners and a square tower at the northwest corner. It consists of three wings around a courtyard on the west side by a battlements surrounding wall pierced by a gate. The great crenellated tower, which dungeon office, is crowned on its summit terrace of a watchtower with a roof shaped pepper shakers. This square building built shale stone mixed with white quartz is the oldest. It has three levels, the first two date from the 14th century, the last level and the spiral staircase from a raising of the late 15th century.
This tower seems more ostentatious than most military as much as the castle was never the castle of Saint-Etienne. One of the ground pavement dwelling is probably contemporary dungeon. The others are the result of rearrangements of the modern era and those of the late nineteenth century and finally repairs arising out the 1944 fire. A park of chestnut trees and cedars surrounds the castle. There is a replica of the Lourdes grotto and a chapel dating back to 1875 in neo-Gothic style.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.
