The Place des Vosges, originally Place Royale, is the oldest planned square in Paris and one of the finest in the city. It is located in the Marais district, and it straddles the dividing-line between the 3rd and 4th arrondissements of Paris. It was a fashionable and expensive square to live in during the 17th and 18th centuries, and one of the central reasons Le Marais became so fashionable for the Parisian nobility.
