Tarbes Cathedral was established during the 12th century. There remain two apses of the choir. A first extension was made in the 14th century by the addition of a Gothic nave. Its extension extended until the 18th century with the outer span. The cathedral resembles a fortress as it was built with round pebbles from the river Adour which have also been used for the construction of many houses in Tarbes. It can accommodate up to 600 people.
A large baroque canopy in marble from the 18th century houses as the main altar.
The cathedral also includes a chapel of the Blessed Virgin in which visitors can read the testament of Louis XVI engraved on a black marble wall three meters high. Another peculiarity is that there is a treasure house and within there are ornaments, chasubles and old bishops' sticks.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.
