El Camp de l'Arpa del Clot (name designated in 2006) is one of the ten neighborhoods of Barcelona which compose the district of Sant Martí, Catalonia (Spain).

At the end of 19th century the two neighborhoods had already strongly changed their appearance and lost a big part of their rural aspect, which characterized them earlier.

They obtained in a few decades the aspect of an industrial center and worker housing due to considerable immigration from all parts of Catalonia and Aragon.

In the last time Camp de l'Arpa has changed a lot losing much of its industrial base and working class, converting itself in a residential area around the testimonies giving evidence of its past.

Examples are buildings such as the old Escola d'Arts i Oficis which today hosts the secondary school called IES Zafra or the old factory Alchemika, which now accommodates a modern public library and as well apartment blocks, which imitate the elegant Eixample buildings and others smaller and more modest ones, which are remaining specially in the smaller narrow streets (called in Catalan passatges) of Camp de l'Arpa, authentic parts which have survived from the 19th into the 21st century, such as Andreví, Aloi, Constancia, Pisto, Puigmadrona, Sospir, all of them very close to Passeig Maragall.
