Close to Emmen, in a sand quarry belonging to the De Boer company, is a world-famous work of Land Art by the American artist Robert Smithson. It was laid out here in 1971 as part of an international exhibition. The work was intended to be temporary but gained such a reputation that it has been preserved. It is the only work by this artist in Europe and can be visited by appointment.
