Two-way street: how Barcelona is democratising public space | The Guardian

At the turn of the 20th century, the Catalan engineer Ildefons Cerdà had a revolutionary idea for extending Barcelona beyond the cramped confines of its medieval walls. In the grid system of the extension he planned, each city block would be built around a large open space or patio, designed to be a park for residents.
When he began his work, the old city was hemmed in physically and psychologically, desperately overcrowded and disease-ridden, with frequent outbreaks of cholera and a lower life expectancy than London or Paris.
