Passeig de Gracia is one of the most significant avenues in Barcelona. In addition to being home to some of the most celebrated architecture in the city, it is considered to be the most expensive street in all of Spain. Originally known as Carni de Jesus, the avenue began as a rural lane connecting Barcelona with the then-independent town of Gracia. Pursuant to an urbanization project in the 1820s, it was transformed into a wide avenue that eventually became a favorite of aristocrats. Today, it is a popular tourist destination, both for its architecture and for its shopping.
By the early 1900s, Passeig de Gracia featured homes designed by notable art nouveau/modernista architects such as Antonin Gaudi, Pere Falques, Josep Puig i Cadafalch, Lluis Domenech i Montaner and Josep Vilaseca. Visitors should take note of the Manzana de la Discordia (the Apple of Discord), a block of Passeig de Gracia located on the southwest side of the avenue between Carrer del Consell de Cent and Carrer d'Arago. Here, you'll find buildings by four prominent architects in clashing styles: the Casa Lleo Morera by Montaner, the Casa Amatller by Cadafalch, the Casa Mulleras by Enric Sagnier, and Gaudi’s famous Casa Batlló. Also see Gaudi's Casa Milà, more commonly known as La Pedrera, with its impressive chimney pots shaped into what look like medieval knights.
Other possible stops along Passeig de Gracia include the Museu del Parfum and the Fundacio Sunol, which features rotating exhibits of 20th century art.
