SS Great Britain in Bristol

You're standing by the Great Britain, the ship that let Isambard Kingdom Brunel turn shipbuilding upside down. First, take in that black hull with its white stripe. Along the stripe you'll spot a row of fake gunports. She was never a warship, though. She was a passenger liner, and a groundbreaking one: the first big ocean-going ship to combine an iron hull with a screw propeller instead of paddle wheels. From 1845 to 1853 she was the largest passenger ship in the world.
