Chandigarh is one of the most significant urban planning experiments of the 20th century. It is the only one of the numerous urban planning schemes of Le Corbusier, the famous French architect-planner, to have actually been executed.This vision of Chandigarh, contained in the innumerable conceptual maps on the drawing board together with notes and sketches had to be translated into brick and mortar. Le Corbusier retained many of the seminal ideas of Mayer and Nowicki, like the basic framework of the master plan and its components the Capitol, City Center, besides the University, Industrial area, and linear parkland. Even the neighborhood unit was retained as the basic module of planning. However, the curving outline of Mayer and Nowicki was reorganized into a mesh of rectangles, and the buildings were characterized by an honesty of materials. Exposed brick and boulder stone masonry in its rough form produced unfinished concrete surfaces, in geometrical structures. This became the architectural form characteristic of Chandigarh, set amidst landscaped gardens and parks.
