Completed in 1774, this wide, tree-lined esplanade is a popular place for Montpellierains to take their evening stroll. The eastern end of the park is marked by the city's 52m-high Arc de Triomphe, dedicated to Louis XIV, not far away from a dramatic statue of the king on horseback. At the western end is the Château d’Eau, an elaborate hexagonal water tower, from where there is a superb view over the wonderful Aqueduc de St-Clément, spectacularly illuminated at night.
In summer, you can climb 88 steps to the top of the arch; contact the tourist office to sign up for one of the guided tours (adult/child €10/6).
