Building Paços do Concelho - Municipal Chamber

The City Hall of Porto is a landmark building first designed by António Correia da Silva, it's called Pacos do Concelho and is at the beginning of the central Avenida dos Aliados. It took several years to build (started in 1920, inaugurated in 1957) and has 6 floors, a basement and 2 courtyards. It's built of marble and granite and occupies an entire city block, the main entrance is on Avenida Aliados at the back of Plaza Trindade, opposite Trinity Church. The side facade caught my attention, as it seems that the stairs of the building go out, in front of this facade is a tourist information office.
