Piazza dei Mercanti is a small historic square just steps from Milan’s Duomo, where arcades and old civic buildings offer a glimpse of the medieval city. Its enclosed feel makes it a welcome pause from the busy streets between the cathedral and Piazza Cordusio.
In the 13th century, the square was the civic and commercial heart of Milan. The Palazzo della Ragione, completed in 1233, served as a seat of government and justice, with trade taking place beneath its open arcade. Look for the relief of the half-woolly sow, linked to a legend about Milan’s origins, and the mounted figure of Oldrado da Tresseno, the official who commissioned the palace. Across the square stands the black-and-white Loggia degli Osii, built in 1316, from whose balcony public announcements were made.
Piazza dei Mercanti is worth visiting for its intimate scale as much as its architecture. Pause by the well, look up at the carved stonework and compare the medieval buildings with the later Palazzo delle Scuole Palatine. It’s an easy stop on a walk from the Duomo towards Castello Sforzesco, and particularly rewarding for photographers and anyone interested in Milan’s history as a trading city.
The square is about two minutes on foot from Piazza del Duomo, served by the M1 and M3 metro lines; Cordusio on M1 is also nearby. Come early in the morning or in the evening for quieter arcades and softer light. Allow around ten minutes for a look, though the surrounding buildings’ interiors are not always open to visitors.
