In the traditional European towns, we often find a large square, which each town calls it "la grand-place ". It is an.open space surrounded by the town's great architectures. This paper attempts to clarify the historical transformation of la grand-place during the 18th century by basing this transformation on the event celebrating the birth of two crown princes, which were held in la grand place of Lille, northern France. In the early 18th century, la grand-place was an area used to held festivals, where citizens gathered to enjoy themselves and admire the central, monumental statue. By the later part of the 18th century, however, it became used more for political or public demonstrations in which the authorities tried to emphasize their power, and by doing so they contributed in forming our modem society.
