==Before the three hillside communities of Siena were established in the 13th century the piazza was an open square used as a market. Walking along the piazza one will notice it was paved in red bricks in a fishbone pattern with ten lines that divide the square into nine different sections. The nine divisions are thought to be symbolic of the rule of the Noveschi, or The Nine, the leaders who were responsible for the splendor of the town in the 13th and the 14th centuries. In the past, as it is today, the piazza was the main center of the city and the focal point of life in Siena.==

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Javier: and tell me Stephanie, what did you hear about this place?
==<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Stephanie: Piazza Del campo is one of Europe's greatest medieval squares. It is renowned worldwide for its beauty and architectural integrity. ==

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Javier: oh yes!
==<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Also, La Piazza was a marketplace established before the thirteenth century on a sloping site near the meeting point of the three hillside communities that coalesced to form Siena: the Castellare, the San Martino and the Camollia. ==

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Now, Andreina tell me about this square from the point of view of an architect. How has brick been used in Piazza del Campo?
==<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Andreina: Well, it was paved in 1349 in fishbone-patterned red brick with ten lines of travertine, which divide the piazza into nine sections, radiating from the mouth of the gavinone in front of the Palazzo Pubblico. == ==<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13px;">Javier:The number of divisions are held to be symbolic of the rule of The Nine (Noveschi) who laid out the campo and governed Siena at the height of its mediaeval splendour between 1292-1355. == ==<span style="font-family: Arial,Helvetica,sans-serif;"> Andreina: in addition, the unity of the Late Gothic houses surrounding the square, is affected in part by the uniformity of the bricks of which their walls are built: brick-making was a monopoly of the commune, which saw that standards were maintained. ==
