It can be cold and windy but it’s always a big celebration.
It’s the biggest event in Norway, their national day 17 May.
Almost everyone are dressed up and go out in the city to watch the big parade.
Schoolchildren marching, waving with flags, playing drums and horns while they screem Hurray for Norway.
Especially in Oslo this is an awesome attraction.
Thousands of people everywhere celebrating and having a happy day.
The parade takes 3-4 hours if you want to see it all.
