Paris is divided into twenty numbered areas known as arrondissements. They are laid out in a clockwise spiral pattern that begins in the city centre, on the Right Bank.
To be found on the Right Bank, the area remained purely rural well into the 19th century, having escaped Baron Haussmann's wholesale redesign of Paris. Technically outside of the city, it enjoyed the status of not having taxes, and as a bonus, the nuns there made wine.
Hence, the charming location dotted with windmills, attracted the Bohemian element and was home to such well-known figures as Erik Satie and Toulouse Lautrec, who found cheap accommodations and camaraderie in the local demi-monde and sleaze pots.
Today it is a schizophrenic area, split between the upscale Yuppy element on one side, and the still bohemian, but more sleazy demi-monde on the other.
Located on the Right Bank, for some reason this district missed out on the influx of starving artists and writers that made neighboring areas prosper. A good many of the original buildings having been constructed in violation of city codes, were torn down and replaced with housing projects.
Today, it is a working class district, with affordable accommodations, but a half hour Metro ride to Paris' more famous spots. It is dotted with houses on elevated areas that have superb views of the Parc des Buttes-Chaumont, for which their owners pay dearly. But residents and visitors alike can find a wide variety of inexpensive dining experiences in the local eateries.
Found on the Right Bank, this was one of the areas which indirectly benefited from Baron Haussmann's tossing the immigrant/working class residents out of more central Paris, during his redesigning in the latter 1800s.
A fringe of communistic characters built up a community on the north side, and late in the reign of Napoléon III, staged a hold-out in Parc des Buttes-Chaumont in 1871.
They were eventually crushed, but the ethnic groups from which they sprung stayed on, and even today, it is known as an area strong in a variety of cultures.
