The most ancient embossed wall in Barcelona

Barcelona has many places of interest, his coast and beaches, the happy neighborhoods of the ancient city (Gothic, Born, Raval...) and much more. We can find also many curiosities among his former streets full of history and anecdotes. Here you are the following one as a sample.
If we place in the Pine Square (Plaça del Pi), just in front of the principal entry of the Pine Church (Església del Pi), we can see a building with a few magnificent embossed walls ("esgrafiados") recently restored, that belonged to the union of the " Tenders Revenedors " (Selling Resellers). This union was born in the XVth century, but they established at this building in the XVIIIth. These baroque embossed walls are done with beach sand, and they are the most ancient of Barcelona.
We observe also a statue of the archangel Sant Miquel, boss of this union.
The front is very well preserved and it's possible to estimate nowadays in all your brilliance (visit this link to accede to the map)
