Ruin of the medieval fortress Hammershus located on the island of Bornholm in the Baltic Sea. While I was visiting Bornholm on vacation it was unfortunately quite windy, so not many days where I could get the drone in the air.
Interesting cave. If it had a bit deeper entranceway it could have been used years ago for a submarine pen. However, the water looks way to shallow for that use.

May have been a secret entrance to the castle perhaps.
Thanks for the comments.
Some believe the fortress as well as the four Round churches of Bornholm (largest of the four is shown in the photo below) was used by the Templar knights and may hide treasures brought back from Jerusalem. So maybe the cave is full of gold
