Subterrànies

Subterrànies refers to underground spaces or structures. This broad term can encompass a variety of environments and creations, both natural and artificial. Natural subterrànies include caves, caverns, and lava tubes, formed through geological processes over long periods. These formations often host unique ecosystems adapted to darkness and specific environmental conditions.

Artificial subterrànies are human-made and serve numerous purposes. Historically, they have been used for shelter, defense, and burial, such as ancient catacombs or defensive bunkers. In modern times, they are utilized for infrastructure like subway systems, utility tunnels, and storage facilities. Underground living spaces or "subterranean dwellings" have also been explored as a way to conserve surface land and maintain stable internal temperatures.

The study and exploration of subterrànies fall under disciplines like speleology for natural formations and civil engineering or archaeology for man-made ones. They present unique challenges for access, safety, and construction due to their inaccessibility and potential for hazardous conditions. Understanding and utilizing subterrànies is an ongoing aspect of human interaction with the Earth.
