Reconstruction following the 1963 earthquake was mainly conducted by the Polish architect Adolf Ciborowski, who had already planned the reconstruction of Warsaw after World War II. Ciborowski divided the city in blocks dedicated to specific activities. The banks of the Vardar river became natural areas and parks, areas  between the main boulevards were built with highrise housing and shopping centres, and the suburbs were left to individual housing and industry. Reconstruction had to be quick to relocate families and to relaunch the local economy. To stimulate economic development, the number of thoroughfares was increased and future urban extension was anticipated.
