Queen Mary was a British ocean liner that was launched in 1934 and became one of the most famous ships of its time. Known for its luxurious design and speed, it served as a transatlantic passenger liner, connecting Europe and North America. During World War II, the ship was converted into a troopship, transporting soldiers across the Atlantic. After the war, Queen Mary returned to passenger service until 1967, when it was retired. Today, it is permanently docked in Long Beach, California, where it serves as a hotel and museum, attracting visitors interested in its rich history and grandeur.
