Bastion V was an unusual work of defense, with significantly prolonged left front. Presumably this deformation was related
to the need of fitting of a bit later city fortifications to older defenses; perhaps the bastion was made up of a combination of two smaller bastions for defense of The Entrance Gate of Lublin. In the foreground there was no natural obstacle that could interfere a potential enemy attack on the gate, with its own artillery cover. Extension of the left (west) front of the bastion and the withdrawal of the curtain IV-V allowed for strengthening the protection of foreground by increasing the number of guns of the fortress that were shielding the foreground gate.
After the abolition of the fortress, the walls of the bastion were blown up, through the damaged right shoulder a new way exit out of town was marked in the direction of Lublin, today Piłsudski Street, the remains of the bastion were neutralized. Today it is virtually unreadable. That is why, on the axis of the former Treaty of Lublin the brick wall, which is now broken, was erected marking the front of the most mysterious bastion of Zamość.
