The amphitheatre of Toulouse-Purpan is constructed on a filled structure, unlike those in Arles, Nîmes, and the Colosseum in Rome, where a hollow structure composed of vaults and pillars supports the tiers. The cavea (the rows of seats intended to receive the public) is fifteen meters wide. This area is separated from the arena by a wall and bound at the outside by a high wall covered in brick. The cavea is divided into equal segments compartmentalized by twenty-three arched horizontal corridors, the vomitoria.
The main entrance to the amphitheatre is located to the north of the arena and is 4.20 meters wide. The arch reproduces the height of the curved vault, which once covered the entry passage. The almond-like arena is sixty-two meters long by forty-six meters wide. Underneath this surface lies an underground network of drains, which leads to a vast ruined well in the center. This well catches the rainwater and allows for the rapid drainage of the arena, even today.
Abandoned at the end of the fourth century, the amphitheatre came to serve as a quarry. In this manner, the monument was completely stripped of its brick facing.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
