Hideaway Fort

This is a highly camouflaged fort I found accidentally while bicycling. Whoever built it is extremely clever, as it is situated in a small patch of trees directly between a country road and a rural route. It's made of the surrounding wood and rock and cannot be seen without knowing it's there or catching a lucky glimpse at the structured pattern of the exterior log wall. Maybe it's used just to hang out or as a bug out shelter. Very strange.
