Kronan, also called Stora Kronan, was a Swedish warship that served as the flagship of the Swedish Navy in the Baltic Sea in the 1670s. When built, she was one of the largest seagoing vessels in the world. The construction of Kronan lasted from 1668 to 1672 and was delayed by difficulties with financing and conflicts between the shipwright Francis Sheldon and the Swedish admiralty. After four years of service, the ship sank in rough weather at the Battle of Öland on 1 June 1676: while making a sharp turn under too much sail she capsized, and the gunpowder magazine ignited and blew off most of the bow. Kronan sank quickly, taking about 800 men and more than 100 guns with her, along with valuable military equipment, weapons, personal items, and large quantities of silver and gold coins.
