Parkpop
The Parkpop festival is a free music festival held annually on the last Sunday of June in the city of The Hague, Netherlands.
It was first held in 1981 and attended by 35,000 visitors. Today up to 350,000 people visit the festival every year. They held the title for largest free pop festival in Europe for a long time. Depending on the source however, there are several claims to this title by other festivals. Przystanek Woodstock in Poland and Austria's Donauinselfest now claim being the second biggest music festival in Europe second only to Radio 1's Big Weekend in the United Kingdom.
The 31st edition of Parkpop was held on Sunday 26 June 2011.
