Loggia degli Osii

The Loggia degli Osii is a Gothic-style civic building of Milan, Italy.

It is located in Piazza Mercanti, a central city square of Milan that used to be its centre in the Middle Ages.

Construction took place between 1316 and 1321, commissioned by Matteo I Visconti, lord of Milan, who wanted a series of porticoes adjacent to the Palazzo della Ragione to house the judicial and notary activities of the city.

Sentences and edicts were proclaimed by the Milanese judges from the Loggia's balcony (known as parlera), decorated with an eagle holding a prey, symbol of justice.

The edifice has a Gothic style portico and loggia in the façade; not usual for the Milanese Gothic structures is the white and black marble decoration: this, more common in Genoa at the time, is perhaps a homage to Matteo Visconti's wife, Valentina Doria.
