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.

Piazza del Campo is a unique place in the whole of the world, starting with the very particular conformation of the ground, which turns the square into a big concave shell. The paving is made of red bricks arranged in fishbone style, divided into a sunburst pattern by nine strips of travertine (in memory of the Government of the Nine, who ruled over the city from 1292 to 1355).

The history of Siena has been made on the Piazza del Campo, or better, 'il Campo', as the Sienese call it. Here the Sienese organised their spectacular and terrible 'games', later replaced by the Palio, where they celebrated and played games of risk (il Campo was the only place where the games were allowed). The market also used to take place here. Il Campo has witnessed the passage of memorable characters in the history of Siena: Santa Caterina, the mystic saint deeply linked to the image of Siena, and also artists such as Simone Martini or Jacopo della Quercia.
The piazza took shape at the end of the 1200s, on a space that was for a long time used for fairs and markets and was situated at a crossroad of important streets. When it was built (the flooring dates back to the 1300s, it managed to hold the entire population of Siena, who gathered here to attend events, tournaments, and buffalo and bull races. Piazza del Campo has hosted almost all the important events in the history of the city, from the time of the Republic up until the Medici period, during which Siena come under the control of Firenze di Cosimo I de'Medici.

Large in scale and ornately decorated inside and out, Siena's cathedral is one of the finest examples of Italian Gothic architecture.

Siena`s Duomo was built between 1215 and 1263 and designed in part by Gothic master Nicola Pisano. His son, Giovanni, drew up the plans for the lower half of the facade, begun in 1285. The facade's upper half was added in the 14th century.

The 14th century was a time of great wealth and power for Siena, and plans were made to expand the cathedral into a great church that would dwarf even St. Peter's in Rome. The already-large Duomo would form just the transept of this huge cathedral.

Expansion got underway in 1339 with construction on a new nave off the Duomo's right transept. But in 1348, the Black Death swept through the city and killed 4/5 of Siena's population. The giant cathedral was never completed, and the half-finished walls of the Duomo Nuovo (New Cathedral) survive as a monument to Siena's ambition and one-time wealth.

In the 19th century, the cathedral was extensively restored, including the addition of golden mosaics on the facade.
