Luke Jerram's Helios is on display at Helsinki Cathedral (Helsingin tuomiokirkko) in Helsinki from 1 October to 1 November 2026. The installation places a seven-metre model of the Sun inside the cathedral as part of the Helsinki Cathedral Parish's Let There Be Light! themed month. The programme links the artwork with discussions of mental health and mental wellbeing.
Helios brings a seven-metre Sun to Helsinki Cathedral
The cathedral's operator lists Luke Jerram's Helios for the period from 1 October to 1 November 2026. The same notice identifies Helsinki Cathedral as the venue and gives its address as Unioninkatu 29, 00170 Helsinki. The cathedral's event notice also places the installation within the building's visitor programme.
Helios is a spherical artwork created by British artist Luke Jerram. It combines imagery of the Sun with light and sound, rather than presenting a static object alone. The artwork's seven-metre diameter gives the installation a physical scale that relates directly to the cathedral interior. The event listing from MyHelsinki confirms the dates and venue and describes the work's visual and acoustic elements.
The Sun installation connects art with the parish programme
Let There Be Light! is presented as a themed month organised by the Helsinki Cathedral Parish. Its stated focus is mental wellbeing and mental health, giving the installation a programme context beyond its visual appearance. Helios therefore serves as both an artwork in the cathedral and the central setting for a month of parish activities.
The connection between the place and the programme is unusually direct. The model is not listed as a city-wide event with a separate venue; it is installed at Helsinki Cathedral itself, where the parish programme takes place. For visitors in October 2026, the artwork provides the fixed point around which the themed month is organised.
What the October programme means for a cathedral visit
The installation changes what visitors encounter inside the building during the stated period. The cathedral remains an active place of worship, so access can be affected by church events and the timetable can vary. The operator directs visitors to its current visiting information before travelling.
The installation also gives the October programme a clear end date. Helios is scheduled to remain at the cathedral through 1 November 2026, so the named period covers October and the first day of November rather than an open-ended exhibition. No separate date beyond 1 November is given in the event information.
