The Town Hall of Montepulciano overlooks Piazza Grande. The building was built in the 13th century in the Gothic style and renovated by Michelozzo during the 15th century. The similarity between the Palazzo Comunale di Montepulciano and the Palazzo della Signoria in Florence is striking, it was personally commissioned by Cosimo I dei Medici. The ground floor is covered in ashlar, while the rest of the facade is in travertine. The battlements of the terrace are in Guelph battlements. Worth seeing are the interiors with the well and the nineteenth-century tombstones. The Palazzo Comunale di Montepulciano is the seat of the town hall. From its tower you can see a splendid panorama: on clear days you can see, from the side of the Val di Chiana the pre-Apennine peaks, Perugia, Subasio, Lake Trasimeno with its islands, and the lakes of Montepulciano and Chiusi.
