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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
