The town of Troyes was very soon surrounded by ramparts; when it was still called Augustobona, it was already surrounded by ramparts which formed a square perimeter, pierced by four gates on each side. The expansion of the city during the reigns of the Counts of Champagne "pushed back" these ramparts to reach, at the end of the 13th century, the shape of the Champagne cork which we know today. As centuries and threats of invasions went on, the first wood walls were replaced by stronger stone walls, supporting many towers and gates located at the strategic entrances of the city. On the outside of the enclosure and all around the ramparts there were also ditches, which were filled with water thanks to the elaborate canal system created by the Counts. These ditches were filled in during the 19th century, and the ramparts destroyed at a time when the narrowness of the city gates condemned them to be demolished and to be replaced by broader streets and boulevards.
Today, the gardens which surround the city and some arches which are still visible on the course of the Canal are the only remains of the ramparts.
