History of Cannon Sloops

Cannon sloops were developed and built dozens of at the Viapori shipyard in the late 18th Century. In battle, cannon sloops were effective due to their mobility and high firepower. The archipelago fleet that was mainly formed of cannon sloops and sloop-of-wars successfully participated in the second naval battle of Ruotsinsalmi in 1790, which is the largest naval battle to have ever taken place on the Baltic Sea. Now, the cannon sloops return to Suomenlinna. The cannon sloop Diana that has been built at Suomenlinna’s shipyard like its 1700s role models, begins its sailings in May.
