>>2819703Mainland Europe should have lots of places like that. The Maginot Line is a series of abandoned military fortifications. There are a lot of remnants of the two world wars. The eastern block countries also have many ruins and ghost towns from after ww2 during the USSR days. Millions starved to death towns and cities collapsed. There's thousands of years of human history in Europe. Unfortunately, I can't point you to any one spot, as I've never had the opportunity to visit myself. I've been to England, Ireland, Germany, Crete and Turkey. But didn't do much exploration outside of the touristy areas.
