Palazzo Pubblico

The Palazzo Pubblico (town hall) is a palace in Siena, Tuscany, central Italy. Construction began in 1297 and its original purpose was to house the republican government, consisting of the Podestà and Council of Nine.

The outside of the structure is an example of Italian medieval architecture with Gothic influences. The lower story is stone; the upper crenelatted stories are made of brick. The facade of the palace is curved slightly inwards (concave) to reflect the outwards curve (convex) of the Piazza del Campo, Siena's central square of which the Palace is the focal point. The campanile or bell tower, Torre del Mangia, was built between 1325 and 1344 with its crown designed by the painter, Lippo Memmi. The tower was designed to be taller than the tower in neighboring rival Florence; at the time it was the tallest structure in Italy. It was fitted with a mechanical clock during the mid 14th century. Its design has been used as the basis for several other campaniles including the Dock Tower in Grimsby, England constructed in 1852 and the Joseph Chamberlain Memorial Clock Tower in the edgabston campus of the University of Birmingham (completed in 1908).

The Copenhagen City Hall and Odense City Hall (Denmark) were greatly inspired by Palazzo Pubblico.
