Much of contemporary Paris is the result of the vast mid-nineteenth 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 urbanisation program involved leveling entire quarters to make way for wide avenues lined with neo-classical stone buildings of bourgeoisie standing. Most of this 'new' Paris is the Paris we see today.
