A man wearing a yellow hard hat and a black jacket with "BZA" on the back opens a wooden door. He is standing at the top of stone steps leading down into a partially subterranean structure. The structure appears to be an earth-sheltered building with a grass-covered roof. The steps are made of stone slabs. The door is old and made of vertical wooden planks with metal hinges and a metal handle. Inside, the room has stone walls and a flagstone floor. The ceiling is arched and made of wood. A skylight is visible in the ceiling. Two men, both wearing yellow hard hats and "BZA" jackets, are seen entering the room from the opposite side, carrying what appear to be wooden shelves.
