The walls you see here are some of the most beautiful I have seen lately in terms of the aging and deterioration of the subtle layering of colors. I am inspired to experiment with encaustic painting for the first time in many years. Encaustic refers to oil-based pigments suspended in heated beeswax.
Some of the other sites I have photographed in Barcelona have already been covered up by the construction of condominiums... how long will this one last?
I did notice on this visit that several clothing boutiques have maintained these types of surfaces within the shops. I ogled the surfaces of the high walls punctuated with steel air ducts longer than I did the 100€ jeans.
Barcelona, Barri de Gràcia Carrer de Siracusa & Torrent de la Olla
...the opposite wall.
