Palazzo della Ragione, Milan

Palazzo della Ragione is the historic civic building opening onto Piazza Mercanti, opposite the Loggia degli Osii. Its name means Palace of Reason, and its earliest role was practical: this was a broletto, a place for administration and justice, built in the thirteenth century. Construction ran from 1228 to 1233, and the architect was Vincenzo Seregni.

The building belongs to Gothic architecture, yet its story includes striking later changes. In 1773, Maria Theresa ordered an enlargement for legal archives, with Francesco Croce adding a storey and reshaping the building in a Neoclassical manner. Look at the façade’s arched openings and the sculpted detail set among them.

The relief of Oldrado da Tresseno recalls the podestà who pursued Cathar heretics with exceptional severity. Nearby, the half-woolly sow appears in bas-relief; its meaning in Milan’s foundation story has remained a subject of scholarly debate. The palace served Milan’s public life until the late eighteenth century, later housed the Banca Popolare di Milano from 1866 to 1870, and returned to archival use until 1970. Its long history is visible in the meeting of medieval masonry, civic power, and contested symbolism.
