In September 1971 the city celebrated its 400th birthday for the first time. In memory of this event, a stele is erected on Revolution Square. Four 18-meter stainless steel pylons symbolize four centuries – the age of the city. At a height of 4.2 m from the ground, the pylons are grasped by a wide steel belt, on which the old and new coats of arms of Kremenchuk are depicted. The authors of the memorial sign are local artists L. Sidorenko and A. Kotlyar.
