Cerda, Founder of a New Discipline - The Science of Urbanization
Cerda developed the concept or urbanization over several years. To do so he was forced to develop a range of conceptual tools, a whole new scientific language, and even the very word Urbanization.

By cutting the corner off each block, Cerda created a small plaza at every intersection this generated alternating street runs and octagonal plazas with 20-metre sides, set at intervals of 133 metres. In addition to the technical advantages, Cerda envisaged the plazas offering prime space for commercial and retail activities, as well as space to accommodate such street activities as street theatre.
