The gardens are located in the 6th arrondissement, right near the Pantheon and la Sorbonne. In 1611 Marie de Medici, who was the widow of King Henry IV of France, decided to construct a new palace in what we now know as the Jardin du Luxembourg. Gardeners were brought in to design the gardens and the original garden (which was only 8 hectares in size at this stage) was designed by Tommaso Francini whom is also responible for the stunning Medici fountain which you will find in the gardens.
Later on the gardens were left mostly unkept. They were extended following the French Revolution, the land confiscated from a neighbouring religious order. Restoration of the unkept gardens were organised by Jean Chalgrin, who was the artichect of the famous Arc de Triomphe. After 1848 the gardens became home to many statues, at first the Queens and notable women of France and later on, monuments to writers and artists. Nowdays the park is a favourite of many for strolling, running, playing pétanque, pony rides, dozing, reading, or having lunch at the kiosk. It is beautiful in all seasons but I think Autumn is especially pretty.
