A kinetic energy absorbing barrier structure, characterized in that it comprises a shell designed to contain a frame in which multiple weights are suitably positioned and which surrounds a tank； the tank is designed to contain a volume of water, gel or other material and defines one or more compartments designed to contain soil for plants； the frame is characterized by having a high capacity of deformation so that the structure is able to absorb the energy deriving from a possible impact, minimizing the movements.
