It would be a shame to miss the changing of the guard which takes place in the palace square at 11h 55 precisely. In the square, you will see cannons from the Louis XIV period, flanked on one side by the promenade Sainte-Barbe, which dominates the Aïl headland, and on the other side by a crenalated parapet which dominates the port.. Starting under an arch, the rampe Major walkway allows you to join up with La Condamine port passing a series of doors from the 16, 17 and 18C.
