The Louvre is the world's largest art museum and a historic monument in Paris, France. A central landmark of the city, it is located on the Right Bank of the Seine in the city's 1st arrondissement (district or ward). Approximately 38,000 objects from prehistory to the 21st century are exhibited over an area of 72,735 square metres (782,910 square feet). In 2017, the Louvre was the world's most visited art museum, receiving 8.1 million visitors.The museum is housed in the Louvre Palace, originally built as the Louvre castle in the late 12th to 13th century under Philip II. Remnants of the fortress are visible in the basement of the museum. Due to the urban expansion of the city, the fortress eventually lost its defensive function and, in 1546, was converted by Francis I into the main residence of the French Kings. The building was extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection. The museum opened on 10 August 1793.
The Louvre's most popular attraction is Leonardo da Vinci's Mona Lisa.
