One of the most evident effects of the Industrial Revolution in the late 19th century was an increasing level of urbanization.

In a global process of population growth, the cities got bigger and changed their face with new avenues, great beautiful buildings, parks and squares, and incorporating the urban improvements that the new technology provided.

These cities were the reflection of the bourgeoisie´s prosperity, showing its growth in the purchasing power and its new ways of leisure, but with a clear segregation of working class in neglected neighborhoods, most of them as a result of a mass immigration.

Cities like London, Barcelona, Chicago, New York and Paris became leading business and cultural centres.
