Helsinki Biennial returns in summer 2027 with an edition built around one of humanity’s oldest subjects: what we do not know.

Titled Unknowns, the fourth Helsinki Biennial will run from June 6 to September 19, spreading contemporary art across Vallisaari Island, Esplanade Park and HAM Helsinki Art Museum.

Curators Mami Kataoka and Arja Miller are bringing together approximately 45 artists and artist groups from Finland and around the world.

The project approaches uncertainty not simply as something frightening, but as a space for curiosity, imagination and discovery.

Science, astronomy, geology, spirituality, mythology and abstraction all enter the curatorial conversation, giving the biennial an unusually broad framework connecting the physical world with human attempts to understand what lies beyond it.

Helsinki Biennial is deliberately distributed across very different environments.

Vallisaari provides the most distinctive setting. The island sits in the Helsinki archipelago and combines forest, rocky coastline, former military structures, and views across the Baltic Sea.

Esplanade Park brings works directly into the everyday life of central Helsinki.

HAM Helsinki Art Museum provides the institutional indoor component of the exhibition.

Together, these locations allow the biennial to move between nature, public space, and museum architecture.

The first group of participating artists announced for 2027 includes Ari Bayuaji, Tara Donovan, Laurent Grasso, Marguerite Humeau, Matias Karsikas, Britta Marakatt-Labba, Ragnhild May, Yoshitomo Nara,

Josefina Nelimarkka, Tawatchai Puntusawasdi, Anna Retulainen, and Jakob Kudsk Steensen.

Additional participants and detailed programming will expand the final exhibition.

Helsinki Biennial 2027: Unknowns Event Overview

Helsinki Biennial 2027: Unknowns – Complete Visitor Guide

Helsinki Biennial began only in 2021, making it much younger than many of Europe’s major recurring art events. Yet its island setting immediately gave it a recognizable identity. By its fourth edition in 2027, the biennial will connect three very different types of space: an island in the Baltic archipelago, one of Helsinki’s best-known public parks, and a major city art museum.

Dates:

6 June 2027 - 19 September 2027

Location:

Helsinki, Finland

Mission:

Unknowns begins from the recognition that human knowledge has always been incomplete. People have mapped stars, studied the body, created cosmologies, and developed scientific systems in an attempt to understand the world. Yet enormous areas remain unexplained. The biennial proposes that uncertainty can generate imagination rather than paralysis. Artists are invited to explore subjects ranging from physical science and astronomy to mythology, spirituality, and forms of abstraction. The curators also connect different cultural traditions, particularly perspectives emerging from Nordic and Asian contexts. The resulting exhibition asks visitors to reconsider not only what humanity knows, but how knowledge itself is created.

Organizer:

Helsinki Biennial is organized by HAM Helsinki Art Museum as part of the City of Helsinki’s cultural program. Arja Miller, Director of HAM and Helsinki Biennial, co-curates the 2027 edition with Mami Kataoka, Director of Mori Art Museum in Tokyo. The project is produced in cooperation with the City of Helsinki and partners including Metsähallitus.

Why attend to Helsinki Biennial 2027: Unknowns?

The setting alone makes Helsinki Biennial different from most major European art exhibitions.

A visit to Vallisaari involves travelling by boat into the Helsinki archipelago and then encountering contemporary artworks along routes through forest, coastal terrain and historical structures.

The journey becomes part of the exhibition.

The 2027 theme also offers artists substantial freedom.

The first announced group already combines internationally established names with artists working across very different media and cultural contexts.

Visitors who enjoy site-specific art, installations, ecological themes and exhibitions that respond strongly to landscape should find the biennial particularly appealing.

Ticket Information

General admission costs

Visitor arrangements differ between the biennial’s locations.

The final 2027 pricing and access details for individual venues and ferry travel should be checked closer to the visit.

Access to Vallisaari requires boat transportation, which should be planned separately when organizing the day.

HAM operates its own museum admission system, while works presented in public urban spaces can be experienced as part of the city environment.

Getting There:

HAM Helsinki Art Museum is located inside Tennispalatsi in central Helsinki and is easily reached by tram, metro or on foot from the central railway station.

Esplanade Park lies between Helsinki’s main shopping streets and Market Square.

Vallisaari is reached by ferry.

Regular ferry services to the island traditionally operate from the Market Square area during the biennial season.

Because access to Vallisaari depends on water transport, visitors should plan their island day around ferry departure and return times.

Accommodation

Central Helsinki is the most convenient base.

Kamppi provides easy access to HAM, while the city center and areas close to Market Square are practical for ferry connections and Esplanade Park.

Kruununhaka, Katajanokka and Punavuori are also attractive options for visitors combining the biennial with architecture, design and other museums.

Helsinki is compact compared with many European capitals, so most central districts remain within easy public-transport distance of the biennial venues.

History & Context of a Helsinki Biennial 2027: Unknowns

Helsinki Biennial is a relatively young event.

The first edition took place in 2021 as a city-wide initiative designed to strengthen Helsinki’s international position as a destination for contemporary art.

HAM Helsinki Art Museum is responsible for organizing the biennial.

From its beginning, Vallisaari has played a defining role in the project.

Rather than placing contemporary artworks exclusively inside conventional galleries, the biennial uses the island’s landscape, history, and architecture as active components of the visitor experience.

Subsequent editions expanded the project’s relationship with the city.

By 2027, the fourth edition will operate simultaneously across Vallisaari, central Esplanade Park, and HAM.

This combination reflects Helsinki’s broader relationship with public art, nature, and urban space.

Tips for Visitors of Helsinki Biennial 2027: Unknowns

Give Vallisaari its own half day.

Trying to combine the island quickly with several other museums will significantly reduce the experience.

Wear proper walking shoes. Parts of the island are uneven and hilly, and the visit involves considerably more walking than a conventional museum exhibition.

Bring clothing suitable for changing coastal weather, even during summer.

Check ferry schedules before traveling to the island and allow enough time before the final return connection.

HAM and Esplanade Park can easily be combined on another day because both are located in central Helsinki.

Visitors with limited mobility should review accessibility information in advance, especially for Vallisaari.

Tips from the ArtExpoWorld

Do not treat Vallisaari merely as an unusual exhibition hall.

The island is part of the artwork experience.

Allow enough time to walk slowly, observe the landscape, and notice how the artists use distance, weather, vegetation, historic architecture, and the Baltic Sea.

If possible, split the visit into two parts: one day for Vallisaari and another for HAM and central Helsinki.

That makes the biennial feel less like a checklist and more like the city-wide project it is meant to be.

Editor’s Note

Many biennials use cities as backgrounds.

Helsinki Biennial goes further by making the geography itself part of the exhibition.

Moving from an urban museum to a public park and then by boat to Vallisaari changes how art is encountered. Distance, weather, landscape, and movement become part of the curatorial structure.

Unknowns is also an unusually appropriate theme for this setting.

The sea, natural environment, and historical layers of the island create a physical reminder that the world remains far larger and less predictable than the spaces we normally control.

For ArtExpoWorld, Helsinki Biennial 2027 is one of the European events worth travelling for rather than simply visiting while already in the city.
