The Belgian National Day is the day which Belgium celebrates on the 21 July each year.
The festival's formal establishment dates to a law of 27 May 1890 and commemorates an event on 21 July 1831 in which Leopold of Saxe-Cobourg swore allegiance to the new Belgian constitution, thus becoming the nation's first monarch. The king's vow marked the start of the independent state of Belgium under a constitutional monarchy and parliament. Says Wickipedia !
While in Brussels the King, Queen and other Royal family members sit on a tribune and watch the parade, in our little town the celebrations are more fun !
After our mayor (below left) had held her speech, the flag was raised, and the anthem finished, everybody mingled together and chatted and greeted people they know.
Orchestras were playing and people dancing and our mayor danced too (below right with the white blouse and the man in blue shorts)
There were lots of games for children
A wall for wall painters where they could paint to their hearts content
and of course a lot of food and barrels of beer !
The day ended with a firework in the evening, apparently it had been very nice, but I was too lazy to watch it so late.
