Since it opened in 1949, Assen has hosted one Grand Prix every year, initially in public roads, next on the track, known also as Dutch TT, since 1955. The circuit lies by green hills that accommodate stands, and it has 64,500 seats. In 2002, renovation work begun in 1999 came to a close.
In 1999, the facility welcomed the new Grandstand, a new control tower, renovated boxes and a new press centre. The track was later modified over the course of the 2005-2006 winter, bringing one of the longest world championship tracks from 6 km. to 4.555 km.
