The church of San Ginés is one of the oldest churches in Madrid. It was one of the churches of the medieval Madrid, of Mozarab origin, from between the 12th and 13th centuries, and its name comes from the fact that it was dedicated to the patron saint of notaries and secretaries, Saint Genesius of Arles (San Ginés de Arlés). it was rebuilt in 1645.
The church is preceded by an atrium enclosed by railings. It has a Latin cross plan, with a nave and two aisles separated by semicircular arches and several side chapels and the altarpieces belong to the Neoclassical-Romantic school. It was, however, totally reconstructed after suffering several fires, so few remnants of the original church, such as the bell-tower, remain. In 1870, the loggia and atrium facing the Calle Arenal were added.
One of the most curious items on display is a stuffed crocodile, which is said to have been brought over from the Americas during the reign of the Catholic Monarchs.
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.
