Suomenlinna is one of the world’s largest sea fortresses, and it sprawls across a series of six small islands. On this walking tour, I’ll show you around, and share the rich history of the island that’s been a UNESCO World Heritage Site since 1991. You'll see the Jetty Barracks which were designed to accommodate 250 soldiers in peacetime, the Suomenlinna Church which was once an Orthodox garrison church and is now an Evangelical-Lutheran church, and the Great Courtyard where you’ll find Augustin Ehrensvärd's grave. As you make your way around the island, I’ll tell you about the Mortuis Memorial Stone, the Military Museum of Manes and the 1918 Prisoner-of-War Camp Memorial which marks the spot where 8,000 prisons were held. While this two-hour tour is perfect for those who want to find out more about the island fortress’ history, we’ll also share some interesting facts about Helsinki and Finland with you. Did you know, for instance, that there are more saunas than cars in Finland?
