Château de La Celle-Guenand was originally founded as a monastery in the 10th century. Later in the 15th century it was reconstructed as a castle. The first known lord of this medieval château was Antoine de Guenand. From the 16th century until 1780 the estate was held by the Coutance family.
Religious conflict in 1779 had led to the removal of the pastor of La Celle-Guenand and the two parishes were merged, to be known as La Celle-Guenand. Jean Cantineau de Commacres lorded over the castle of La Celle-Guenand until 1785 the last years of the French monarchy. Followed by Pierre Gaullier to midway through the French Revolution until 1794.
The château was restored in the 17th century as a private Residence and additional outbuildins were built in the 19th century. Today it functions as a Bed & Breakfast hotel.
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.
