Explored the massive abandoned underground WW1/WW2 Bunker "Monte Lesco" near Rijeka, Croatia. Inside the haunting long tunnels and insane spiral staircases, I explored alone, hearing strange noises. Its otherworldly feel was like the backrooms or a real-life SCP. Join me on this crazy adventure. Original Music By: / @joestmusic #adventure #backrooms #abandoned #ww2 #history #explore
