L’Eixample was built in the mid-19th century according to engineer Ildefons Cerdà’s urban project: a squared street layout with chamfered corners and interior patios in every block. With the highest representation of Catalan Modernist architecture in the ‘Quadrat d’Or’ (golden square), around Passeig de Gràcia, the district is divided in two by Balmes street. The left part, that ends approximately in Sants Estació, has emblematic buildings such as Universitat de Barcelona.
