Carrer de Sants is a high street in the eponymous neighbourhood of Sants, in Barcelona (Catalonia, Spain). After being designated officially a commercial road in 1999 by shopkeepers' associations of its district, it is often claimed to be Europe's longest commercial road, spanning also Carrer de la Creu Coberta (which is essentially the same street). [1] [2][3] The Sants-Montjuïc district council has its seat there. [4]
