Santa Catalina Monastery construction started in in 1393, in a Romanesque style when Gothic standards were already taking hold. With Mendizábal's disestablishment (1837) the Franciscans were obliged to abandon the monastery, and the building's ownership and management passed to the army until the year 2000.
The monastery has two cloisters, the best conserved of which is in Renaissance style. The church was modified in the 18th century, when it changed from a cross-shaped ground plan to a single nave covered with a barrel vault on arches. Coloured wooden retable with Baroque ornamental designs. Some of its images are in churches in Ferrol. Inside the monastery, we can see the remains of capitals, statues, tombstones. Other sculptural remains from the 16th century can presently be seen in the San Antón Archaeology Museum (A Coruña).
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.
