The forest, which sits not far from Schiphol Airport where flight MH17 took off on its way to Kuala Lumpur, contains 298 trees – one for each person who perished when the plane crashed in Ukraine's Donetsk region on July 17, 2014, Sky News reported.
The monument takes the shape of a ribbon and was inspired by the black memorial ribbon used to symbolise mourning after the atrocity.
It also features a surrounding ring of sunflowers that will bloom each July.
