Finland's centennial Independence Day parade begins in the eastern city of Kuopio around noon.
Yle Areena is streaming the event live, with highlights on TV1 beginning shortly after 5 pm. For military buffs, the highlight is the march past Kuopio City Hall, starting at 13.10.
Some 1200 people and 50 vehicles are taking part. The event is being organised by the Karelia Air Command, which will participate with 41 airplanes and helicopters.
Defence Forces hardware, including a Hornet fighter jet, is also on display at Kuopio's Market Square from 10 am to 3 pm.
