Welcome to Derinkuyu, an underground city that once housed up to 20,000 people. In the Cappadocia region, famous for its cave dwellings and underground villages, Derinkuyu stands out for sheer size and complexity. Locals began digging in the 500s BCE. The city consists of over 600 doors, each of which can be closed from the inside. Each floor could be closed off as well. And just to make attacking completely impossible, the entire city was deliberately built without any logic. Its maze-like layout makes navigating the city nightmarish for unfamiliar invaders.
Photographer Lassi Rautiainen recently captured the profound partnership between a she-wolf and a brown bear in the wilds of northern Finland. For days, he witnessed the strange pair meet every evening to share food after a hard day of hunting. No one knows when or how this relationship was formed, “but it is certain that by now each of them needs the other.” - Source
