Suomenlinna

Helsinki

When I booked my flights out to Helsinki, one of the places I was most excited about visiting wasn’t actually in the city itself; it was 20 minutes away.  By boat.

Built during the Swedish era (1748-1808) as a maritime fortress and a base for the archipelago fleet, Suomenlinna (formerly known as ‘Sveaborg,’ or Viapori’ in Finnish) is Helsinki’s 18th century sea fortress.

Not only is Suomenlinna unusual in the shape of its construction but also in the fact that it has defended three different sovereign states since its initial construction.  During the Russo-Swedish war in 1808, the fortress fell to the Russians and remained under the rule of the Russian Imperial Government for 90 years.  Ownership then passed to the Finnish government in 1918 and it was at that point that its name was changed from ‘Viapori’ to ‘Suomenlinna’ – meaning ‘Castle of Finland’ – to reflect the country’s independence.

Nowadays it's one of the most popular tourist attractions in Finland and also one of the most popular day trips from Helsinki.

Suomenlinna, or the Fortress of Finland was so cool. We spent an entire day on this island. So much to do and see! #helsinki #finland #blue
