It would be a shame to miss the changing of the guard in the palace square at 11:55 on the dot, all the more so as it is the heart of the Rocher. In the square, you will see 17C-18C cannons, flanked on one side by the promenade Sainte-Barbe, which dominates the Aïl headland, and on the other by battlements which dominate the port. Starting under an arch, the Major walkway extends to La Condamine, passing 16C, 17C and 18C doors.
