The Loggia dei Militi is a Gothic loggia built in 1292 on the east side of the Piazza del Comune, originally serving as the assembly hall of the city's militia. It is a small but elegant building — five round-headed arches on slender columns opening onto the piazza, with decorative relief carving above and a corbelled cornice at the roofline. The proportions are finely judged and it holds its own compositionally against the much larger cathedral and tower.
The building is now used for cultural events and exhibitions; the ground floor loggia is generally open and accessible. It is one of three civic buildings that complete the Piazza del Comune ensemble along with the Palazzo Comunale and the Palazzo Cittanova, and its scale is perfectly calibrated to the space — neither too large nor too small.
