This year the Queen visited Zeeland on Queen's Day but it was celebrated in villages and cities all over the country.
'Hoe beleef jij Koninginnedag 2010?' How do you experience Queen's Day 2010? - the theme of the video competition - was an idea of The Prince of Orange and Princess Máxima of The Netherlands.
The winning videos can be seen on its YouTube channel.
My three favourites:
In the pouring rain, a young boy started playing his recorder before 9 A.M. He was still playing at Noon!
Queen Beatrix, HRH The Prince of Orange and Princess Máxima receive gifts from admirers in Middelburg.
Chalk drawings done by children show the atmosphere on Koninginnedag in the village of Lonneker, a few miles north of Enschede (Province of Overijsel).
The winners have been invited to Noordeinde Palace and will also get a tour of the Royal Mews.
