Filtering Hall

Did you know that The Finnish Museum of Technology operates in more than one historical building?

We admit that the museum grounds are notoriously difficult to navigate with all the similar-looking buildings. We are keeping two different buildings open to the public: the round, yellow Main Building with more traditional museum exhibitions and the red brick Filtering Hall.

The Filtering Hall is a different kind of museum experience where you can follow in the actual footsteps of Helsinki water purification employees in a milieu restored to its 1930's appearance. The building was originally built in 1909 to house the pumps, main electric switchboard and water filtration pools used to deliver clean drinking water for Helsinkians. You can imagine running to your post upstairs using the beautiful but less than practical spiral staircase and step into the literal last footsteps of a technician who got on the bad side of the electric switchboard (which is totally safe and currentless today, we promise)!

Legend tells that the technician never left his post, not even when the water purification plant was converted into a museum in 1969.

Unfortunately the Filtering Hall isn't entirely accessible, but you can reach the upstairs pools by contacting the museum Info in the Main Building.

Come hunt some ghosts (but please don't harm him, we're quite fond of him) or experience an authentic industrial milieu in its original setting! The Filtering Hall is open all year round according to the opening hours of The Finnish Museum of Technology excluding possible special events. The venue is available for rent for private or public events.

Entry included in the ticket for The Museum of Technology (available in the Main Building).
