FIELD: construction engineering. SUBSTANCE: this relates to design of walls primarily of such premises which are intended for storing valuables in banks, museums, and other similar institutions. Wall of protected premise includes reinforced concrete structure which is made up of load-bearing layers. Reinforced concrete structure has space, which contains loose material in the form of bodies which can freely turn or rotate relative to center of their mass when pressure is applied off their center. Space for containing loose material has slots through entire height and length of wall and in lateral cross-section of wall in at least part of its height. Located in parallel are space creating components. Distance between these components is equal to at least three maximal values of linear dimension of bodies of loose material, and/or they can have widenings towards base through not less than by one tenth part of its height preferably from side of base. Used in function of loose material are bodies made of material of high-hardness preferably of hardened steel, cast iron, and/or natural or artificial stone and/or glass. Used materials must allow for free movement of bodies under gravity at changing of space volume in case of braking integrity of wall. At least part of load-bearing layer of concrete which limits slot space in wall as to its thickness and/or its height is made with dispersed filling of concrete preferably by steel fibres with length If to correlate to condition b>=If≅0,5h, where b - minimal thickness of concrete from surface of space creating components to rod reinforcement, h - minimal thickness of concrete from surface of space creating components to surface of structure. Rod reinforcement of concrete structure of wall has protrusions for introducing them into ceiling slab and/or into base slab. Aforesaid embodiment of wall ensures its higher protection against unauthorized penetration through it into protected premise. EFFECT: higher efficiency. 6 cl, 12 dwg
