The Eixample (; ) is a district of Barcelona between the old city (Ciutat Vella) and what were once surrounding small towns (Sants, Gràcia, Sant Andreu, etc.), constructed in the 19th and early 20th centuries. Its population was 262,000 at the last census (2005). Architecture and design The Eixample is characterized by long straight streets, a strict grid pattern crossed by wide avenues, and square blocks with chamfered corners (named illes in Catalan, manzanas in Spanish). This was a visionary, pioneering design by Ildefons Cerdà, who considered traffic and transport along with sunlight and ventilation in coming up with his characteristic octagonal blocks, where the streets broaden at every intersection making for greater visibility, better ventilation and (today) some short-term parking areas. It also provided an area for horse-drawn wagons and carriages to easily turn around. The grid pattern remains as a hallmark of Barcelona, but many of his other provisions were ignored: the four sides of the blocks and the inner space were built instead of the planned two or three sides around a garden; the streets were narrower; only one of the two diagonal avenues was carried out; the inhabitants were of a higher class than the mixed composition dreamed of by Cerdà. The important needs of the inhabitants were incorporated into his plan, which called for markets, schools, hospitals every so many blocks. Today, most of the markets remain open in the spots they have been from the beginning. Some parts of the Eixample were influenced by Modernista architects, chief among whom was Antoni Gaudí. His work in the Eixample includes the Casa Milà (nicknamed La Pedrera) and the Casa Batlló, both of which are on the wide Passeig de Gràcia, as well as the Sagrada Família. Other architects who made highly significant, and certainly more numerous, contributions to giving the Eixample its characteristic appearance include Josep Puig i Cadafalch, Josep Domènech i Estapà, Josep Vilaseca i Casanovas and perhaps above all Enric Sagnier i Villavecchia, responsible for a total of over 500 buildings in the city (not all of them in the Eixample). The Casa Terrades, better known as Casa de les Punxes and replete with medieval allusions, stands at the junction of Av. Diagonal with Carrer Rosselló. It was built in 1903–1905 by the Modernista architect Josep Puig i Cadafalch, who used Nordic Gothic and Spanish Plateresque resources side by side, along with traditional Catalan
