How much can places change over time?

In 1974, French writer Georges Perec spent three days observing Place Saint-Sulpice, a public square, in Paris. While doing so, he took notes, about events and non-events – the whole idea was an experiment to capture a particular place in a literary and experimental way. Places are the visible manifestation of complex social interdependencies, which, beyond the obvious function of a place, provides information about its history and its relationship to the present, e.g. about its creation, preservation, destruction or appropriation, about ownership and power.
