This is a bridge over the dunes leading to praia do monte velho, Portugal. I lost a gopro under that bridge on a cold night in November 2015. I was doing a timelapse with it of my activities that night. I went back in the early morning but it was gone.
It doesn't look like it's a bridge but it is about 1 meter off the ground. It looks closer to the ground on the photo because of the lack of shadow caused by the red light under the bridge. The blue was a remote controlled light behind me and I walked behind the camera for the green.
