Avinguda Diagonal, Major avenue in Barcelona, Spain.
The roughly 6.8-mile-long (11-kilometer) thoroughfare cuts diagonally across Barcelona, passing through Les Corts district in the west, Eixample, Gràcia, Sarrià-Sant Gervasi and Sant Martí in the east.
Engineer Ildefons Cerdà designed the avenue in 1859 under Queen Isabella II's commission as part of the Eixample expansion plan, which connected Barcelona's medieval core with surrounding towns.
The roughly 165-foot-wide (50-meter) thoroughfare links business districts with residential areas and houses numerous shopping centers, office towers and sports facilities that shape daily life for Barcelona residents.
Several metro lines run beneath the avenue with stations at regular intervals. Dedicated bike lanes provide cyclists with a continuous east-west connection through the city without significant elevation changes.
During different political periods, the street received multiple name changes, including Gran Via Diagonal under the Republic and Avenida del Generalísimo Francisco Franco during the dictatorship, before regaining its current designation.

Barcelona offers a wide range of architectural and cultural sites that reflect centuries of Catalan history. The city combines Gothic churches and medieval streets with the organic forms of Antoni Gaudí's modernist buildings. From the Sagrada Família to Parc Güell, his designs shape the cityscape, while the Gothic Quarter and palaces such as Palau Güell represent earlier periods. Museums including the Picasso Museum and Joan Miró Foundation illustrate the city's artistic legacy. Markets like La Boqueria and Sant Antoni provide insight into Catalan daily life. The waterfront district of La Barceloneta, the Olympic Port, and Montjuïc with its cable car and fountain broaden the range. Other destinations include Casa Batlló, Casa Milà, the Hospital de Sant Pau, the National Art Museum of Catalonia, and the Aquarium.
