We took the ferry over to the island fortress originally called Sveaborg since it was built by the Swedish. Called Viapori by the Finnish and renamed in 1918 to Suomenlinna. Sewden began construction of the fortress in 1748 against Russian expansion.
The ferry only took about 15 minutes.
While on the island we got to tour a Finnish submarine.
We also explored the military museum.
Once we were back, we had dinner and then more beers!
I tried multiple beers from this brewery, Donut Island, and enjoyed their diverse range.
