The Eixample is a historic district of Barcelona between the old city and what were once surrounding small towns (Sants, Grącia, Sant Andreu etc.). Constructed in the 19th and early 20th centuries, some parts of the Eixample were heavily influenced by modernist architects, chief among whom is Antoni Gaudķ. His work in the Eixample includes the Casa Milą and the Casa Batlló, both of which are on the wide Passeig de Grącia, as well as the Sagrada Famķlia.
