Passeig de Gràcia
 & L’Eixample

This sweeping boulevard lined has extravagant wrought-iron lampposts and smart designer boutiques. It’s the elegant backbone of L’Eixample, the 19th-century extension to the city built when the old city walls tumbled, and the results of the wealthy competing with one another to create the most fabulous mansions. Modernista masterpieces now rub shoulders with each other, from Gaudí’s Casa Calvet on Carrer de Casp to Puig i Cadafalch’s crazy Casa 
de les Punxes (House of Spikes).
