The Holland Pop Festival, also known as the Kralingen Music Festival, was a pop and rock music festival held in the Kralingse Bos, in the Kralingen neighbourhood of Rotterdam in the Netherlands, from 26 to 28 June 1970.^[1]

Performing bands included The Byrds, T. Rex, Santana, Jefferson Airplane, and the headlining Pink Floyd. Approximately 100,000 attended. Festival posters show that the festival was billed in Dutch as Pop Paradijs and 'Holland Pop Festival 70', and that the main investor was Coca-Cola.^[2] In both English and Dutch, the festival is also known by the English name Stamping Ground, and is often billed as the European answer to Woodstock.^[1][3][4] It took place approximately one year after Woodstock, and two months before the third 1970 Isle of Wight Festival (the first two being held in 1968 and 1969).

The Festival became an influential event, as it turned out to be the actual beginning of the Dutch tolerance policy towards marijuana.^{[citation needed]} The many present undercover cops did not arrest any of the users or small traders: it became clear that there were just too many, and all of them peaceful.^{[citation needed]}

In 1971, a documentary about the festival appeared, titled Stamping Ground, created by Hansjürgen Pohland aka Jason Pohland and George Sluizer. The film was made for an international audience and is also known under the titles Love and Music, and in Germany Rock Fieber. Also, several books and exhibitions have been dedicated to the event. A triple lp-boxset was released in 2010. The Dutch Festival 1970 (Kralingen) was organized by Foundation "Holland Pop Festival" (Piet van Daal, Georges Knap, Toos v.d.Sterre, Berry Visser)

On 21 September 2013, a memorial has been unveiled in the Kralingse Bos area, to commemorate the first multi-day open air popfestival on the European continent.^[5]
