Gran Via de les Corts Catalanes

With a length of 13.1 km (8.1 mi), it is the longest street in Catalonia and the 2nd longest in Spain, after Gran Vía de la Manga, in La Manga del Mar Menor, but is the one with most street numbers in Spain.

The late 19th century urban planner Ildefons Cerdà included it as an essential part of his draft of the new "Projecte de reforma i eixample de Barcelona" (nowadays simply known as "Pla Cerdà"), as a wide road linking a number of villages around the coastal part of Barcelona, and called it Lletra N, Número 11.

It was renamed Corts in 1900, as a reference to the Medieval and Early Modern Catalan Courts.

With the restoration of democracy, its name became Gran Via de les Corts Catalanes in 1979.

Line H12 of Barcelona's BRT network traverses Gran Via on its entirety.
