If you ever get to the southern Alps of Italy you'll find a lot more lost places barely accessible by foot, if at all. Also a lot of old mines, contraband trails and houses can be found in the area around Iselle close to the Swiss border. It's sometimes amazing what you see there, some of those abandoned areas will have 100+ houses (build by hand).

Just one stunning object among many: http://www.amici-del-leader.it/Home/Montagna/Le%20escursioni... (Villa Lancia, Valle Olocchia)

Edit: Maybe also entertaining for some, old stone pits where the Italian left everything behind in the mountain, including cars https://alpi-ticinesi.ch/foto/gallerie_foto.php?id=190&foto=...
