Kauppatori Ferry Terminal

Sail Through Helsinki's Fortress Archipelago

Board the JT-Line ferry at Kauppatori and watch Helsinki's skyline dissolve into the military archipelago that defined it. Count Uspenski Cathedral's 13 gold domes from the water — each one paid for by the Russian merchant community that bankrolled Helsinki's Grand Duchy era. Spot Suomenlinna's walls, the fortress that turned a failing port town into a strategic capital. The 20-minute crossing is the city's origin story told in salt water.
