eix

Eix is a Catalan noun meaning axis or main line. In general use, it refers to a central line, spine, or framework around which something is organized. The term is common in geography, urban planning, and mathematics, where it denotes a principal route, direction, or reference line.

In the context of Barcelona, l’Eixample (often shortened to “el Eix” by locals) is a well-known urban district created in the 19th century as the city expanded beyond its medieval walls. The plan, designed by Ildefons Cerdà, features a rectilinear grid with chamfered street corners to improve traffic flow, light, and ventilation. The district lies north of the old town and forms a dense, mixed-use area that preserves a strong sense of city structure and order.

L’Eixample is renowned for its Modernisme architecture and urban character. Notable landmarks include Gaudí’s Casa Batlló and Casa Milà (La Pedrera), as well as a concentration of shops, cafés, and cultural venues along major avenues such as Avinguda Diagonal and Gran Via de les Corts Catalanes. The district is typically divided into areas known as Dreta de l’Eixample (right side) and Esquerra de l’Eixample (left side), reflecting its broad, orderly plan.

Beyond Barcelona, the word eix is used in Catalan-speaking regions to describe principal urban axes or routes. In summary, Eix denotes a central organizing line, with l’Eixample in Barcelona serving as a landmark example of planned urban expansion and its architectural heritage.
