Piazza del Campo is the great civic square of Siena in central Italy, a concave brick basin where the medieval city seems to flow down its hillsides into a single space. Its distinctive form emerged under the Government of the Nine in the late thirteenth and early fourteenth centuries, when Siena’s rulers reshaped an earlier market field into the organised centre of a powerful republic.Government of the Nine
A sloping medieval square shaped like a shell
Piazza del Campo occupies a natural hollow where the territories of three hill communities met, a site that long functioned as a field and marketplace before it acquired its brick surface and regular architectural frame.meeting point of the three hillside communities The square’s plan is often described as resembling a shell, a result of following the steep topography while drawing a clear perimeter that gathers the surrounding streets into a single open space.“snail-shell” shape
The paving of Piazza del Campo is one of its defining features, laid in bricks on edge with radial bands that divide the surface into nine segments converging towards the lowest point in front of the Palazzo Pubblico.brick paving divided into nine segments These divisions echo the period when the Government of the Nine ruled Siena between 1287 and 1355, and they still give the square a subtle pattern that visitors see in changes of brick orientation and pale stone lines amid the red surface.paved in 1349 with brick and travertine
From market field to the seat of a republic
Long before its brick paving, the space known as the Campo served as a marketplace at the confluence of important roads, with documented references dating back to 1169 that cover both today’s Piazza del Campo and the nearby Piazza del Mercato.first documented mention dates to 1169 During the thirteenth century the city council acquired land in the valley and gradually separated the Campo from the Mercato, giving each square a distinct role in Siena’s commercial and civic life.subdivision between the two piazzas
Under the Government of the Nine, ruling from 1287 to 1355, the Campo began to take on its present form as a controlled civic space framed by coherent facades and governed by strict architectural rules.statutes on palace facades and windows Statutes obliged palaces facing the square to adopt regular openings, and guidelines issued in 1297 coordinated the construction of civic buildings and the shaping of the piazza so that political gatherings and public festivals could be held in a setting that reflected the ambitions of the Sienese republic.guidelines in 1297
Palazzo Pubblico and Torre del Mangia on the brick basin’s edge
On the lowest side of Piazza del Campo stands the Palazzo Pubblico, the brick-built town hall that became the seat of Siena’s republican government at the beginning of the fourteenth century.Public Palace built between 1288 and 1342 Construction of this palace began in the late thirteenth century, and by 1310 the Government of the Nine had taken up residence there, looking out over the square that was being progressively paved and refined.Palazzo Pubblico rose from 1297
