This park got its name because it was wedged between the 16th-century fortifications and those that followed a century later.

Next to Place de Neuve it is also home to the oldest university building, erected in 1873. On June 21 the Parc des Bastions puts on concerts as part of the international Fête de la Musique.

Life-sized chessboards are available to all passersby, and there are also ping-pong tables and then a skating rink in winter.
