When Titanic departed on her doomed maiden voyage in April 1912 she was the largest, most luxurious and most technically advanced ship ever to sail the seas.
Her electrical plant could produce more power than an average city power station at the time and her features included Turkish baths, a swimming pool, gymnasium, and - even in third class - some of the best accommodation available at sea.
Now - 114 years after the ship hit an iceberg and sank in the north Atlantic - the technical plans and drawings used to build her will be made available to the public for the first time.
They are among hundreds of thousands of ship plans and documents made widely accessible.
Titanic - along with her sister ships Olympic and Britannic - was designed at the drawing office of the Harland & Wolff shipyard in Belfast, which is now a hotel.
