Muraille gallo-romaine

In the 3rd century, to protect themselves from Alemanni and Frankish invasions, the Romans built a thick wall 800m long. Augustomagus then withdrew into a castrum of 6 ha ensuring the security of the administration and its inhabitants: the Sulbanectes. Built according to the Roman technique using the alternation of stones and bricks to ensure its solidity, the wall of Senlis is one of the rare constructions of this type, preserved in its quasi-entirety in France. You can still admire 16 of the original 30 towers. Part of this wall is hidden in private properties. Do not miss the best viewpoints on the wall: - In the Jardin du Roy with the stone and brick towers, - In the Park of the Royal Castle where the wall delimits its enclosure, - Rue de la Treille with the "Fausse Porte ", an opening directly in the wall, - The Jardin de l'évêché, rue aux Flageards where it was partly destroyed to make way for the cathedral and the existing part of which was converted into a room to house the works of the Museum d'Art et d'Archéologie - When you pass through Square Vernet, take a good look so as not to miss the statue of a little man in the wall -Rue de Villevert where the wall was destroyed to allow carts, horses and now the cars. The base of the wall is based on recycled materials (columns, statues, etc.). You can discover these foundations in situ at the Museum of Art and Archeology revealing exceptional elements, coming from destroyed monuments, assembled dry on a height of 3 or 4 seats.
