Contest #176 answer: Celestial Vault, Kijkduin, The Netherlands

This is another land art piece of James Turrell. It is not well known and a lot smaller than his Roden Crater project.
It is called ‘Hemels Gewelf‘ (Celestial Vault) and was constructed in 1996.
It lies in the sand dunes of The Hague and is open to the public.
Kudos to who found it without the hint, because I thought this would be a very difficult one.
