A war. A word that evokes feelings of anxiety, fear and danger in each of us. However you can hide in an underground bunker. There are three floors in mine bunker. Each of them has a square open space and small chambers, which are used in many different ways: as a place to sleep, as a bathroom or a storeroom. It is possible to move along the bunker by a spiral staircase or by an elevator. Both of them run to a cabin above the terrain, where light enters only from the inner square atrium.
