After the Fountain of the Virgin, the main street narrows and slopes down towards the large lime tree of the bastion of the gateway below. Picturesque buildings line the sides of this unevenly paved alleyway. The large lime tree was planted in 1713 and has witnessed many historic events. From here, you can contemplate the parkland of the Favart estate (formerly the Potter estate) and imagine the old feudal castle. Beneath this esplanade is the entrance to an old casemate. To get to this "prison", you have to descend the "white stones" very carefully, as the slope is so steep.
