The urban fabric of Legnano has developed around the [[old town]]; its growth was influenced by three barriers: the [[Olona]] River, the ''strada statale del Sempione'' and the [[Domodossola–Milan railway]].{{sfn|D'Ilario|Gianazza|Marinoni|Turri|1984|p=347}}

The city was the protagonist of a progressive [[urbanization]] that led to a considerable expansion of the population center.{{sfn|D'Ilario|Gianazza|Marinoni|Turri|1984|pp=347–357}} At the origin of this phenomenon was the birth of many [[Industry (economics)|industries]] that attracted workers from different parts of Italy. As can be seen from the [[Demographic transition|demographic evolution]], between 1871 and 1921 the population of Legnano quadrupled. Due to the need for water, the mussel industries born in the 19th century sprung up along the shores of the Olona.{{sfn|D'Ilario|Gianazza|Marinoni|Turri|1984|p=347}} As a result, the new residential districts have occupied the free areas beyond the river valley.

As a result of the growth of Legnano, the companies have built their locations more and more on the outskirts. Then, the various [[Financial crisis|economic crises]] that followed in the decades of the 20th century led to the birth of many [[Brownfield land|brownfield sites]] that are recovering.{{sfn|D'Ilario|Gianazza|Marinoni|Turri|1984|p=352}} The most important urban intervention, which was carried out at the beginning of the 21st century, was the recovery from the former [[Cotonificio Cantoni]], an area of 110,000 square meters that was destined to [[Residential area|residential]] and [[commercial area]].
