The largest and most luxurious passenger steamship in the world, the Olympic-class
RMS Titanic was owned by the White Star Line and constructed at the Harland and
Wolff shipyard in Belfast, Ireland. She set sail for New York City from Southampton, England with 2,223 people on board. Some of the most prominent people of the
day were travelling in first class.
