In perpetual renovation and evolution, the Diagonal Avenida crosses Barcelona from its point of demarcation with the city of Esplugues to the Forum by passing through many unmissable sights of the city such as the Palau Reial, the Plaça Francesc Macià, the district of Gracia, the Plaça de las Glories and many others.
The wide Avenida Diagonal runs through Barcelona from the southwest of the city, in the University area, to the northeast in the Diagonal mar district, at the foot of Barcelona's beaches.
