The church of Exmorra is a small one-aisled church from the 13th century. In ca. 1300 the nave was lengthened and a tower was added. Of this tower, which collapsed in 1836, only the lower part remains. That same year the wooden tower and the western facade were built. Until the church was restored in 1963-1966 it was covered with a thick coat of plaster, underneath which many traces of its original Romanesque condition had been preserved. The big windows in the nave were replaced by smaller ones on the north side. On this side the wall has a peculiar curve. In the south wall thelarger windows, which are probably from the 19th century, remained.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.
