Let's return to the origins of the city.
In the 1930s, the subdivisions developed: these are the current neighborhoods of the Clos and Vélizy-Bas. The pavilions of the Breguet city are also born.
The city of Vélizy-Villacoublay is occupied by the German troops between 1940 and 1944. The air base is the objective of the bombing allied to 6 times. The one of August 24, 1943 was particularly murderous for the commune, the bombs having touched the quarters of houses.
After the Second World War, Vélizy-Villacoublay was declared a "disaster-stricken city" on September 3, 1945, and in 1952, the Secretary of State for War awarded the Croix de Guerre a national homage to the inhabitants of the commune. In 1958, the town was declared an Urbanized Zone by Priority. In the 1960s, Vélizy-Villacoublay underwent profound changes.
Under the impetus of Robert Wagner (Mayor of Vélizy-Villacoublay from 1953 to 1988), the city was entrusted with the task of constructing a comprehensive urban plan in agreement with the Ministry. The plan is drawn up by the urban planner Robert Auzelle in collaboration with the architect Alain Gillot. The Grand ensemble of Vélizy-Villacoublay was born. In three major phases, the city takes on its present appearance: the central district (the Mall district) emerges from the land between 1963 and 1966, then in the west (the Mozart district) from 1966 to 1970, (The Louvois district) from 1969 to 1975 and an economic zone (the Vélizy 2 regional shopping center and two lifestyle satellites and the Usine Center).
