The Porte Saint-Jean dates from the 14th century. and takes its name from the Saint-Jean-Baptiste chapel. This is one of the three main gates of the walled city. At its creation, it was equipped with crenellations and barbican. Then it was rebuilt in 1758 in its current form, during the modifications made to the southern rampart. In 1866, the municipality had erected a statue of the Virgin in golden cast iron, with the inscription: Posuerunt me custodem", which translates to "They made me their guardian".
