Diemerpark is the largest urban park in Amsterdam with an area of around 90 hectares, making it about twice as large as the famous Vondelpark in Amsterdam-Centrum.

Diemerpark, located between IJburg and the Amsterdam-Rhine Canal, was opened in 2004 and offers numerous recreational opportunities for visitors.

Research showed that the pollution did not pose a direct danger to humans and animals, but because of the construction of IJburg, plans were made to clean up the area.

Because of the extent of the pollution, the area was "wrapped" underground by sheet piles and covered with a waterproof top layer consisting of bentonite clay and foil.

As a result, visitors are not allowed to dig holes, and it is not possible to leave deep-rooted trees of more than 5 meters high there.

There are now a large number of animals in the natural area, around 200 species of birds, grass snakes, shrews, nightingales, bluethroats, kingfishers and others.

[7] In addition, around 200 plant species have been counted and some mammals have returned to the nature park, including deer, bats and stoats.
