Open House Helsinki 2026

Open House Helsinki opens doors to architectural landmarks in Helsinki that are normally closed to the public. The event features guided tours through buildings, interiors, and urban sites - both contemporary and historic architectural works. Tours are led by architects and experts.

The 2026 theme is architecture competitions, and the programme includes projects created through these competitions - from individual buildings to entire city districts. The event is part of the Finnish Association of Architects' 150th anniversary celebration of architecture competitions.

The programme will be announced on Thursday, August 13, and registration opens on Thursday, August 20. The event takes place September 3-6, 2026 in Helsinki. Admission is free.
