A major avenue in Barcelona, you can see the handiwork of Gaudí and Pere Falqués.
Chanel and Burberry have stores along the main street, Passeig de Gràcia. Before Barcelona's expansion and the building of the new city in the 1800s, this was the road to the town of Gràcia, hence the name. The famous block of discord will be the first example of the diversity in architecture that began when the wealthy started buying up space in the new Eixample and showed off by hiring the coveted architects to build ever-stranger and more opulent homes in the trendy modernist style.
The Block of Discord is on the Passeig de Gràcia between Consell de Cent and Argo. Be sure to stop at Casa Batlló. The façade alone is remarkable with its skull-like window treatments, undulating serpent-like roof in shiny blue, and the enchanting, curvaceous, Art Nouveau interior.
