Suomenlinna is a fortress situated over six islands in Helsinki, Finland. The fortress was built by the Swedish in the 18th century. It was designed by Augustin Ehrensvard and built on six rocky islands. It was used by the Swedish Army and Navy until it was lost to Russian forces in the early 19th century. The fortress was taken under Finnish control after Finland gained independence in the early 20th century. The fortress which is a short boat trip away from the centre of Helsinki is now a quiet peaceful place open to explore and enjoy.
