Explore a 175-year-old military

Explore a 175-year-old military: Explore a 175-year-old military bunker in the Netherlands. Built in 1874 as a WWI bomb shelter, this place has been forgotten and left to ruin by the tides of time. Geologists prove that the place has been preserved just as it was left because the sea level has risen over the years, leaving the bunker to be encased in the sand.
