The Pavillon de Marsan or Marsan Pavilion was built in the 1660s as the northern end of the Tuileries Palace in Paris, and reconstructed in the 1870s after the Tuileries burned down at the end of the Paris Commune. Following the completion of the joining of the Louvre and the Tuileries in the 1850s and the demolition of the Tuileries' remains in the early 1880s, it is now the northwestern tip of the Louvre Palace. Since 1897 it has been part of the Musée des Arts Décoratifs, a separate institution from the Louvre.
