The Queen Mary is a retired British ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard-White Star Line. After several years of decreased profits for Cunard Line, the Queen Mary was officially retired from service in 1967. She left Southampton for the last time on October 31, 1967, and sailed to the port of Long Beach, California, where she was permanently moored. The City of Long Beach bought the ship to serve as a tourist attraction featuring restaurants, a museum, and a hotel. The ship has remained in Long Beach ever since.

Over the years, the Queen Mary has been used for various purposes, including as a troopship for Allied soldiers during World War II. She was also involved in an accident in 1942 when she accidentally sank one of her escort ships, slicing through the light cruiser HMS Curacoa off the Irish coast with a loss of 239 lives.

Today, the Queen Mary is a popular tourist attraction in Long Beach, California, featuring various exhibits and tours that highlight the ships history and grandeur.
