context_page_description: The Palazzo Pubblico is a palace in Siena, Tuscany, central Italy. Construction began in 1297 to serve as the seat of the Republic of Siena's government, which consisted of the Podestà and Council of Nine, the elected officials who performed executive functions.
context_section_description: The outside of the structure is an example of Italian medieval architecture with Gothic influences. The lower story is stone while the upper crenellated 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. At the top of this facade is a huge round flat bronze plate [Christogram], the symbol used by Saint Bernardino. It was placed there by the government in 1425 in gratitude to the great preacher, a native Sienese, for his sermons aimed at quelling social and political factionalism and unrest. <needs citation>
  The campanile or bell tower, Torre del Mangia, was built between 1325 and 1344; its crown was 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 Edgbaston campus of the University of Birmingham, which was completed in 1908.
