The SS Great Britain is a historic steamship designed by the engineer Isambard Kingdom Brunel. Launched in 1843, it was the first iron-hulled, steam-powered vessel to cross the Atlantic Ocean, marking a significant advancement in maritime technology. After serving as a passenger liner, the SS Great Britain was retired in 1933 and later restored. Today, it is preserved as a museum ship in Bristol, England, where visitors can explore its innovative design and learn about its role in the history of ocean travel.
