Olympic and Titanic
The Olympic-class ocean liners were a trio of ocean liners built by the Harland & Wolff shipyard for the White Star Line in the early 20th century. Although the three were the largest and most luxurious of their time, two were lost early in their careers:Titanic sank on 15 April 1912 after hitting an iceberg in the North Atlantic, and HMHS Britannic sank on 21 November 1916, after hitting a mine laid by the German minelayer, U-79, triggering one of the mines laid in a barrier off of Kea during World War I. Olympic, the eldest sister and namesake of the class, continued in service until she was laid up and scrapped in 1935, alongside Cunard's RMS Mauretania.

Although two of the three vessels did not have successful careers, they are among the most famous ocean liners ever built. Decorative elements of Olympic were purchased to adorn many places in England (and even a cruise ship, Celebrity Millennium).Titanic's story has been adapted into many films and books, and Britannic has also inspired a movie of the same name.
