The Helsinki City Council celebrates its 150th anniversary this year. In honour of this landmark, the City of Helsinki is arranging an Open House at City Hall on Helsinki Day, Thursday 12 June, from 8.30 to 10.20. The tour will provide a behind-the-scenes look at the historical building and how local government works.

The Helsinki City Hall will open its doors to the public on 12 June, Helsinki Day, welcoming all those who wants to learn more about decision-making in the city. The Open House event will allow visitors to tour the building’s premises and learn more about its architectural features and artwork. 

Tours will lead visitors from the City Hall lobby to the mayor’s reception room and its adjacent balcony looking out over the Market Square. From there, they will continue to the historic Banquet Hall, the City Council Chamber and its public gallery. In addition to the architecture and art, the tour will also highlight the city’s decision-making processes and the history of the Helsinki City Council and the City Hall building.
