The 3rd Class didn’t have a real promenade but they had three exterior areas that acted as promenades. It occupied the forward & aft end of C Deck and the aft end of B Deck. The Forward Well Deck was used as a promenade. The Aft Well Deck was used as another promenade in the stern. The Poop Deck, although really cluttered, acted as another promenade.
The Poop Deck and Aft Well Deck was where passengers and any remaining crew gathered in the final moments of the ship's sinking.
