The Loggia della Mercanzia , also known as Loggia di Banchi , is one of the most representative buildings in the historic center of Genoa and was one of the first stock exchanges in Europe, built at the end of the 16th century.

It is a unitary space, without internal support structures and covered by a large pavilion vault supported by large arches. Today it is home to cultural events and exhibitions.

On the back wall of the Loggia della Mercanzia there is a fresco , made at the end of the 16th century by the Tuscan painter Pietro Sorri , depicting the Madonna enthroned with the Child and Saints John the Baptist and George, patrons of Genoa. The painting was saved from the fire following the bombing of 1942, while the one in the vault, by Giovanni Battista Brignole, depicting the coat of arms of the Republic of Genoa, was destroyed.

Outside, the space above the arches is decorated with a series of bas-reliefs depicting trophies of arms, made by Taddeo Carlone.
