The Palais du Luxembourg is better known as the "Sénat", in reference to the house of Parliament to which it is home. Construction began in 1715 for this architectural gem built for Marie de' Medici. Its magnificent heritage is visible throughout its hallways.

By visiting the many rooms of the Senate building, one can discover great works of art and architecture, including the Library's annex and reading room, the State Messengers' room, the Hall of Busts, the staircase of honour, the conference room, and the room where the visitors' book is kept. To see the legislative body in its full function, you can attend a session that is open to the public.

As early as 1750, the palace devoted a wing to art, the Palais du Luxembourg Royal Painting Gallery. At the time, visitors admired paintings by Rubens, Leonardo da Vinci, Rubens, Veronese, Titian, Poussin, Van Dyck, Rembrandt, and more.

Its garden is a haven of greenery, said to be one of the most beautiful in the world. It is partially laid out in French style, and decorated with sculptures.
