Château de Launac was built by the viscounts of Gimoes in the 12th century. In 1148 the castle passed into the house of Isle Jourdain. Dismantled after the Treaty of Paris in 1229, the fortress was rebuilt in the fifteenth century by Carmaing Nègrepelisse. It consisted of four corner towers including an old keep from the twelfth century.
This castle was undoubtedly again dismantled by Cardinal Richelieu under the reign of Louis XIII. Today two wings remain. Inside the castle is a monumental fireplace and painted decorations from the XVth century.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.
