Along the southern section of the walls, on the railway station square, there is the most representative tower of the ancient Roman perimeter, named du Pailleron because it was long used for hay storage.
The tower, with a square floor plan and open on the four sides with six big windows, three for each level, is inserted in a part of roman walls which was open in the middle ages to build the so called “Porta Ferriére”.

After being damaged by fire, at the end of the 19th century the tower was subjected to a careful restoration work using brick, under the supervision of Alfredo d’Andrade.

Not open to visitors.
