What Tervasaari is
Tervasaari (“Tar Island”) lies just off Helsinki’s coast and is connected to the mainland by a pedestrian causeway. Once an industrial hub for storing tar used in Finland’s maritime trade, it is now an urban park with green spaces, cultural events, and views of the city, within walking distance of central Helsinki.
Today, the island features a historic granary, rose gardens, an amphitheatre, and Helsinki’s only official dog swimming area. For information about events and facilities, see the City of Helsinki’s official website, MyHelsinki, and Lonely Planet.
History and transformation
Tervasaari’s name reflects its original use as a tar-storage island. Because tar was hazardous and posed a fire risk, storing it away from the densely built city helped protect Helsinki (Vihreät sylit).
The first tar granary was built in 1805 by merchant Petter Heidenstrauch. For more than a century, the island was a secure storage point for tar and other hazardous goods (Vihreät sylit). The wooden granary from 1805 is now a protected structure, and information plaques explain the island’s change from industrial storage site to recreational park (Evendo).
The Tervasaarenkannas causeway was built in 1939, connecting the island to the mainland. After the last cement factory closed in 1970, Helsinki reclaimed land and repurposed Tervasaari as a public park. Architect Lars Liljefors guided the transformation, and a 1995 redevelopment project introduced varied plantings, event spaces, and improved infrastructure (Vihreät sylit).
The redevelopment reflects Helsinki’s approach to adaptive reuse and sustainable urban planning, turning a former industrial site into a community hub (PlanetWare).
