Ancient labyrinths under the moon

Just love to visit places like this and of course at night to do photography.
This place is a cult place with graves, a 500m long ceremony road and several labyrinths.
The ceremony road is straight north-south and they walked this road with dead people to bury them, it is as old as at least 1000years, the vikings used it.
The view over the big water of Mälaren was beautiful, I can only imagine how wonderful it must have been 1000 years ago.
The big hills of the graves must had been an impressive sight from the water when the passed by with boats.
