Did you notice: National Defence Day on 27 September in Tuusula
How does Finland prepare for crises? What can individuals do to ensure their own safety? Answers to these questions will be sought in Tuusula on Saturday, 27 September 2025. Uusimaa National Defence Day is an event for the whole family, offering information and experiences for both children and adults.

This annual event organised by reserve associations brings together the Finnish Defence Forces, security authorities and voluntary national defence organisations. In the exhibition area, you can see, for example, a Leopard battle tank, a NASAMS air defence missile system, and rescue services’ equipment and vehicles. Traditional cannons, a parade and a Hornet flyover are part of the day’s programme. The event is open to everyone, and admission is free.
The event offers a great opportunity to learn about the wide range of leisure and educational activities offered by the organisations. The main themes are exercise and sports, outdoor and wilderness skills, shooting and traditional activities.
“Volunteer national defence actors are an essential part of the overall security field. They train, practise and support the authorities in maintaining preparedness,” says Mats Fagerström, chair of the event’s organising committee.
The main celebration of National Defence Day at the Monio Cultural Centre will be opened by Mayor Janne Mellin. Member of Parliament and member of the Defence Committee Timo Heinonen will speak at the celebration. Internationally renowned opera singer Ville Rusanen will perform as a soloist with the Guards Band.
At the National Defence Day event held at the Tuusula Sports Centre, you can chat with representatives from various organisations and find your own way to strengthen collective security. The event offers the public a concrete view of how national defence and overall security are built in everyday life.
