This was taken at Enoura Observatory, Japan. It was the one of the entrances to the Optical Glass Stage with Amphitheater Seating. A walking trail made from steel boxes cuts through the Seating and leads to the stage. At the end of the trail stands a Tome-ishi, a.k.a. Stop stone to warn visitors not to go further. This spot is quiet and private. It allows me to see the shape of the seating, the glass stage and the ocean view in the background from within. I just can't get enough of it.
