“Barcelona's famous grid district takes its name from a Catalan verb meaning to widen.”
The word eixample comes from the Catalan verb eixamplar, meaning to widen or expand. That verb traces through Old Catalan to the Latin amplus, meaning spacious or large, with the prefix ex- indicating outward movement. Catalan speakers reshaped the infinitive into their own phonology over many centuries. By the time Ildefons Cerdà used the noun in his 1859 urban plan, eixample had long been ordinary Catalan for an extension or enlargement.
Cerdà submitted his Pla de l'Eixample to the Spanish government in 1859, after Barcelona's medieval walls came down in 1854. His plan covered roughly 22 square kilometers of farmland north of the old city with a grid of 133-by-133-meter blocks. Each block had chamfered corners at 45 degrees, creating octagonal intersections that let light into the streets. The Spanish government approved the plan in 1860, overruling the city council, which had preferred a rival scheme by Antoni Rovira i Trias.
The Eixample filled in unevenly across the 19th and 20th centuries, with wealthiest families occupying the Quadrat d'Or along Passeig de Gràcia. Cerdà had intended the inner courtyard of each block to stay open as communal garden space. Property developers built into those courtyards almost immediately, turning Cerdà's green lungs into warehouses and rear buildings. The gap between plan and execution became a recurring subject in Barcelona's architectural debates for over a century.
Urban planners in the late 20th century rediscovered Cerdà's Eixample as a model for walkable, dense city blocks. The chamfered corners, long dismissed as aesthetic, proved to improve pedestrian visibility and traffic flow. Barcelona began opening interior courtyards to the public in the 1990s through small parks. Today the word eixample has traveled into urban planning literature in its Spanish form, ensanche, as a reference point for humane grid design.

Eixample now refers most specifically to the Barcelona neighborhood, but the word carries its original force intact. When Catalan speakers say they live in the Eixample, they are using a noun that once described any act of making room, of pushing boundaries outward. The neighborhood is so completely identified with Cerdà's grid that the word has narrowed from a general concept to a proper name. Other cities have their ensanches and extensions; only Barcelona has its Eixample.
The precision of the word suits the precision of the plan. Eixample is both the act and the outcome, the verb made stone. To name a neighborhood after the act of making space is to admit that the city's true subject is not its buildings but its appetite for room.
