Graça Convent is one of the oldest convents in Lisbon. According the legend, in 1362 the statue of Our Lady of Grace appeared in the network of a fisherman. The convent part is nowadays used by the army and is not open for visits, but the church is still in use.
Most of the original Graça Church collapsed in the earthquake of 1755, so what you see today is an 18th century baroque monument. Inside it is partly decorated in 16th and 17th century tiles, while outside is Sophia de Mello Belvedere (famous Portuguese poet ) which is one of the city's most popular viewpoints.
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.
