Helsinki Cathedral (Helsingin tuomiokirkko) is hosting Luke Jerram's Helios during the Tulkoon valo! programme, which runs until 1 November 2026. The programme combines the artwork with discussions, music, services and family activities in Helsinki, Finland.
Helios and the Tulkoon valo! programme run through 1 November
The parish's official programme places Tulkoon valo! at the cathedral from 1 October to 1 November 2026. The theme for 2026 is mental health and wellbeing, with the programme also addressing exclusion, hope and future perspectives through public discussions and encounters.
The centrepiece is Helios, a Sun installation by British artist Luke Jerram. The cathedral parish says the programme includes panel discussions, Hope Dialogues, concerts, services and a silent disco, while a family space adventure invites children to explore the artwork through questions and creative activities. The official programme details place these elements within the cathedral's themed month.
A seven-metre Sun changes the cathedral visit in October
Helios measures seven metres across and represents the Sun as a detailed scale model. The family activity page says its imagery draws on 400,000 photographs of the Sun and observations collected by NASA, giving the installation a scientific dimension alongside its use as a setting for public discussion.
The relationship between artwork and building is central to the programme: the Sun hangs in the cathedral while conversations about mental wellbeing take place around it. Visitors can choose a shorter activity route inside the cathedral or a longer route that continues to the Old Church, with some tasks located in the Cathedral Crypt. The family adventure listing confirms the cathedral address and the period through 1 November 2026.
The building is at Unioninkatu 29 beside Senate Square. Trams 2, 4, 5 and 7 stop at Senate Square, and the University of Helsinki metro station is the nearest metro stop, according to the cathedral's visitor information. These transport links place the final days of the programme within Helsinki's central civic district.
