Early History and Strategic Location

Vallisaari—meaning “Embankment Island”—lies between Suomenlinna and Santahamina, its position making it a linchpin in Helsinki’s maritime defenses. Known as Lampisaari (“Pond Island”) in the Middle Ages, its freshwater ponds were crucial for passing ships (Wikipedia; Environment & Society Portal).

Military Eras: Swedish and Russian Rule

Swedish Rule (13th Century–1808)

Under Swedish control, Vallisaari supported the Suomenlinna fortress, serving as a wood depot and livestock pasture. Extensive logging stripped the island of its forests by the early 20th century (Wikipedia).

Russian Rule (1808–1917)

The Russian Empire fortified Vallisaari as part of the Krepost Sveaborg defense network, constructing batteries, barracks, and a granite road for Emperor Alexander II’s 1863 visit (Helsinki Biennial).

Finnish Independence and 20th Century Use

Upon Finnish independence in 1917, Vallisaari remained a military zone, serving as an ammunition depot and technological outpost, including a WWII-era German Freya radar station. Despite its military function, a civilian community flourished mid-century, complete with a school, shop, and social activities. A deadly 1937 explosion in the “Valley of Death” left its mark; by the 1990s, the island was abandoned (Finland.fi).

Post-Military Era and Nature Recovery

With the cessation of military use in 2008, Vallisaari’s flora and fauna rebounded. The island now harbors Helsinki’s most diverse ecosystem: over 1,000 butterfly species, rare bats, and the city’s only alder swamp (Wikipedia; Helsinki Biennial). Some plant species were introduced during the Russian era, reflecting the island’s layered history.
