Illa de la Discòrdia

The Illa de la Discòrdia or Mansana de la Discòrdia —English: Block of Discord; Spanish: Manzana de la Discordia—is a city block on Passeig de Gràcia in the Eixample district of Barcelona, Spain. The block is noted for having buildings by four of Barcelona's most important Modernista architects, Lluís Domènech i Montaner, Antoni Gaudí, Josep Puig i Cadafalch and Enric Sagnier, in close proximity. As the four architects' styles were very different, the buildings clash with each other and the neighboring buildings. They were all built in the early years of the 20th century.
The block is the southwest side of Passeig de Gràcia, between Carrer del Consell de Cent and Carrer d'Aragó. The houses are the Casa Lleó-Morera, at Passeig de Gràcia 35, designed by Lluís Domènech i Montaner; Casa Mulleras, at Passeig de Gràcia 37, designed by Enric Sagnier; Casa Bonet, at Passeig de Gràcia 39, designed by Marcel·lí Coquillat i Llofriu; Casa Amatller, at Passeig de Gràcia 41, designed by Josep Puig i Cadafalch; and Casa Batlló, at Passeig de Gràcia 43, designed by Antoni Gaudí. Due to the presence of these famous landmark buildings, the block is a significant tourist attraction in Barcelona.
