Not just the famous ones like the balconies of Gaudi's "la Pedrera" and of other prestigious buildings, but the balconies of buildings of less ostentatious construction that make the bulk of the "Eixample": that large area of Barcelona that was planed and built at the turn of the 19th and 20th centuries to house the ordinary citizens of Barcelona. 

The decorative details in these buildings are a credit to the landlords who, it seems to me, were filled with a sense of civic pride and, putting aside economic considerations, allowed their architects and their builders to leave behind them a heritage of good taste and beauty that is unique to Barcelona. What a pity that this tradition ended in the "twenties"! 

The austere and functional buildings constructed since then are reminiscent of "nínxols", where the dead are stacked up to rest. A cynic might say that, similarly, the artistically dead nowadays return home every night to be stacked up to rest in these uninspiring constructions.
