In 1907 Picasso paints Les Demoiselles d'Avignon, considered one of the first Cubist paintings...
Logically, it is not a faithful portrait of a print, nor does it pretend to be. But... is there anything left of the brothel in which Picasso was inspired to make this painting, at 44 Carrer d'Avinyó? We can walk up and down it and find no trace of it - the maximum, some reproduction of the famous painting.
But you can take a walk around Carrer Escudellers, Carrer de la Carabassa and Carrer Ample, you will be able to see a carassa. From the end of the medieval period and well into the 19th century, brothels in Barcelona were advertised with a stone face on the facade, sometimes above a door or window, sometimes under a balcony, or in a corner that indicated it was nearby... on which facade is the carassa from this block?
