The 1st arrondissement of Paris is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is colloquially referred to as le premier. It is governed locally together with the 2nd, 3rd and 4th arrondissement, with which it forms the 1st sector of Paris (Paris-Centre).

The Louvre, or the Louvre Museum, is a national art museum in Paris, France. It is located on the Right Bank of the Seine in the city's 1st arrondissement and home to some of the most canonical works of Western art, including the Mona Lisa, Venus de Milo, and Winged Victory. The museum is housed in the Louvre Palace, originally built in the late 12th to 13th century under Philip II. Remnants of the Medieval Louvre fortress are visible in the basement of the museum. Due to urban expansion, the fortress eventually lost its defensive function, and in 1546 Francis I converted it into the primary residence of the French kings.
