Paris Architecture
"Modern" Paris is the result of a vast mid-19th century urban remodelling. For centuries the city had been a labyrinth of narrow streets and half-timber houses, but beginning in 1852, the Baron Haussmann's vast urbanisation levelled entire quarters to make way for wide avenues lined with neo-classical stone buildings of bourgeoise standing; most of this 'new' Paris is the Paris we see today. These Second Empire plans are in many cases still applied today, as the city of Paris is still imposing the then-defined "alignement" law (building facades placed according to a pre-defined street width) on many new constructions. A building's height was also defined according to the width of the street it lines, and Paris's building code has seen few changes since the mid-19th century to allow for higher constructions. It is for this reason that Paris is mainly a "flat" city.
Paris's unchanging borders, strict building codes and lack of developable land have together contributed in creating a phenomenon called muséification (or "museumification") as, at the same time as they strive to preserve Paris's historical past, existing laws make it difficult to build within the city limits the larger buildings and utilities needed for a growing population. Many of Paris's institutions and economic infrastructure are already located in, or are planning on moving to, the suburbs. The financial (La Défense) business district, the main food wholesale market (Rungis), major renowned schools (École Polytechnique, HEC, ESSEC, INSEAD, etc.), world famous research laboratories (in Saclay or Évry), the largest sport stadium (Stade de France), and some ministries (namely the Ministry of Transportation) are located outside of the city of Paris. The National Archives of France are due to relocate to the northern suburbs before 2010. The need for a larger Paris is largely acknowledged by the French government. As of November 2007, discussions for such a larger Paris have begun, though which suburbs should be included in this larger Paris is unresolved. In any case, such an extension will not occur before the French city-hall elections, scheduled in the spring of 2008.
