Suomenlinna

A massive sea fortress spread across islands outside Helsinki, once used as both a military stronghold and a prison.

Suomenlinna, known as the “Gibraltar of the North,” is a UNESCO World Heritage site located just off the coast of Helsinki. Constructed by Sweden beginning in 1748, the fortress was designed to defend against Russian expansion and became one of the largest sea fortifications in Europe. Over time, it changed hands between Sweden, Russia, and Finland, bearing witness to centuries of warfare and political upheaval.

Beyond its military role, Suomenlinna has a darker legacy. Parts of the fortress were used as a prison, with harsh conditions for those held within its walls. During the Finnish Civil War in 1918, it became the site of a grim prison camp where thousands of Red prisoners were confined under brutal circumstances, many perishing from disease, starvation, and executions.

Today, Suomenlinna is both a cultural landmark and a reminder of these turbulent times. Visitors can explore the vast network of walls, tunnels, and bastions, while exhibitions recount both its strategic importance and its role in human suffering. The haunting history of its prison years remains an integral part of the fortress’s story.

Location: Located on a group of islands about 4 km from central Helsinki.
