Helsinki and the Suomenlinna-Sveaborg Sea Fortress

A day trip to Helsinki, Finland, from Tallinn, Estonia, with Tallink’s luxurious ferries — Shuttle Star and Baltic Princess. In Helsinki we took the opportunity to visit a UNESCO World Heritage Site — the 18th century sea fortress on the island of Suomenlinna. Helsinki owes its very existence to this remarkable fortress. 10 April 2012.
