The utility model refers to the field of construction, to be exact, to underground structures for year-round storage of food products. The technical result of the proposed utility model is to increase the strength of the cellar while maintaining its low weight and durability. Solving the technical problem in a cellar containing a body in the form of a vertically disposed hollow cylinder of a polymeric material sealed to the bottom of a polymeric material and having an overlap of polymeric material with a neck for user access inside the enclosure, equipped with a ladder, shelves of polymeric material and a supply- exhaust ventilation, is achieved by the fact that the shelves are rigidly connected to the cylinder of the body, forming an internal frame of rigidity, and have flanges along the inner edge, there are vertices located racks, which are rigidly connected with the overlapping, shelves and bottom, the bottom of the body is made of two-layered, on the entire surface of the outer layer of the bottom there are stiffeners, on the outer surface of the cylinder there are eyelets with holes, the ladder is made of aluminum. Cylinder, bottom, floor, shelves and pillars of the casing can be made of polypropylene. The racks can serve as ducts for ventilation because they can be moved out of the cellar, with the gate with the air flow adjustment damper located at the top of the first pillar, the gate with the air intake control valve is located at the bottom of the second pillar. In the holes of the eyes, a cable can be installed to fix the cellar over the anchor plate. 6 ill. and on the entire surface of the outer layer of the bottom there are stiffeners, on the outer surface of the cylinder there are eyelets with holes, the ladder is made of aluminum.
