The Jardin du Luxembourg (French pronunciation: [ʒaʁdɛ̃ dy lyksɑ̃buʁ]), known in English as the Luxembourg Garden, colloquially referred to as the Jardin du Sénat (Senate Garden), is located in the 6th arrondissement of Paris, France. It was created beginning in 1612 by Marie de' Medici, the widow of King Henry IV, for a new residence she constructed, the Luxembourg Palace. The garden today is owned by the French Senate, which meets in the Palace. It covers 23 hectares (56.8 acres) and is known for its lawns, tree-lined promenades, tennis courts, flowerbeds, model sailboats on its octagonal Grand Bassin, as well as picturesque Medici Fountain, built in 1620. The name Luxembourg comes from the Latin Mons Lucotitius, the name of the hill where the garden is located.
