The Place des Vosges, originally the Place Royale, is the oldest planned square in Paris, just before the Place Dauphine. It is located in the Marais district, and it straddles the dividing-line between the 3rd and 4th arrondissements. It is an enclosed square, accessible via a main street on one of its four sides and two streets running beneath pavilions. It was a fashionable and expensive square to live in during the 17th and 18th centuries, and one of the main reasons for the chic nature of the Marais among the Parisian nobility. Along with the Place des Victoires, the Place Dauphine, the Place Vendôme and the Place de la Concorde, it is one of the five royal squares in Paris.
