I have to admit that there are many interesting facets of Barcelona (or 'Barna' for short) which don't qualify as pomo... here's some of the unique features of this beautifully quirky city:
Check out the pavement!
Casa Mila / La Pedrera, designed by Antonio Gaudi
A paperback vending machine
Window complex at Casa Battlo
The exterior of the Sagrada Familia
Marilyn Manson posters at a typical fast food restraunt... actually, wait! This *is* postmodern!
A street carnival with jubilant onlookers
Custo display with colourful cactus-like construction
Do YOU have a Brief Question(TM)?
Mosaic on the ceiling of a Park Guell construction
Lollies at the markets
A Joan Miro painting of his favourite town, Montroig
A painting of Pablo Picasso's from his Rose Period
