The Monastery of St. Stephen was founded by St. Antoninus Cantacuzene, who is thought to be a son of the Serb ruler Nicephorus II of Epirus, in c. 1400.
This monastery rests on the plain rather than on a cliff. It was shelled by the Nazis during World War II who believed it was harboring insurgents and was abandoned. The monastery was given over to nuns in 1961 and they have reconstructed it into a flourishing nunnery, with 28 nuns in residence in 2015.
The old katholikon (main church), which was rebuilt in 1545 and frescoed shortly thereafter, still stands. The new katholikon was built in 1798 and is currently being frescoed by a modern artist. It is dedicated to the martyred St. Charalambos, whose head it contains.
The refectory (15th century) has a surviving fresco of the Virgin in the apse. The monastery contains a small museum of vestments and other religious objects and the nuns sell handmade embroideries and other trinkets.
Monasteries of Meteora are included on the UNESCO World Heritage List.
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.
