22@, also known as 22@Barcelona and Districte de la innovació is the corporative name given to an urban renewal area in Barcelona's formerly industrial area of Poblenou, in the district of Sant Martí, nicknamed "the Catalan Manchester" in the 19th century. Its aim is to convert Poblenou into the city's technological and innovation district, as well as to increase leisure and residential spaces. Centered on Plaça de les Glòries Catalanes, it is part of one of Europe's biggest urban regeneration schemes, begun during the 2000s and still ongoing, spanning 115 blocks. The plan was approved in 2000 by the city council when the new 22@ land designation was introduced, replacing the 22a designation, used in city zoning.
