Governors’ Promenade is at the base of La Citadelle’s stone curtain walls. You will be humbled by their enormity. From Cap Diamant, you will first encounter the Prince of Wales Bastion. This section featured a 13.25 ton cannon. Next is this Mann Bastion, built in 1829. Further along is Cap Diamant Redoubt. Constructed in the late 17th century, this oldest section was a menacing platform for eight cannons. Finally, in the corner, is the King’s Bastion from 1821. Positioned here is a ten ton cannon named Rachel. She was capable of hitting a ship in the river up to 1.5 miles away.
