Helsinki Cathedral hosts Tulkoon valo programme until 1 November

Helsinki Cathedral (Helsingin tuomiokirkko) is hosting the Tulkoon valo! programme in Helsinki from 1 October to 1 November 2026. The month-long programme combines Luke Jerram’s Helios installation with discussions, music, religious services and family activities.

Tulkoon valo brings Helios to Helsinki Cathedral until 1 November

The programme is devoted to mental health and mental wellbeing. The cathedral’s operator says that art and cultural events, dialogues and worship will explore the importance of mental health and create opportunities for public discussion.

Helios, created by British artist Luke Jerram, remains on display throughout the programme. The installation is a model of the Sun that combines visual art, light and sound. It provides the setting for conversations about mental health, life, hope and the future.

The programme includes four panel discussions involving experts, researchers and public figures. Their themes include social exclusion, hope, young people’s wellbeing and the importance of care. The organiser’s programme announcement for Tulkoon valo also lists music events and services during the period.

Helios links the cathedral’s programme with family activities

The installation is not presented as a stand-alone exhibition. Its presence connects the cathedral’s religious programme with a wider cultural month, giving the building a role as a venue for discussion as well as worship.

A Family Space Adventure runs at the cathedral from 1 October to 1 November 2026. The activity uses art and space-themed questions to help families explore Helios and can be completed in a shorter format at the cathedral or as a longer route leading to the Old Church.

MyHelsinki describes the activity as suitable for families and says that some parts are located in the cathedral crypt. The event therefore adds a self-guided element to the same installation that anchors the Tulkoon valo! programme. Details of the dates and venue appear on the family space adventure page.

The cathedral stands at Unioninkatu 29 in central Helsinki. The operator’s event notice confirms the address and identifies the building as the venue for the October 2026 programme. It also places the Helios installation inside the cathedral for the duration of Tulkoon valo.

The programme gives the building a changing cultural context during October. Visitors encounter an active church venue, a contemporary artwork and a schedule that treats mental wellbeing as a subject for public conversation. That combination distinguishes the current programme from a visit centred only on architecture.
