For many , the most enchanting spot in town is the late-17th-century Promenade du Peyrou ' spacious classical gardens with a triumphal arch , an equestrian statue of Louis XIV , and , on a mound at the far end , a hexagonal chateau d 'eau ( water tower ) that looks more like a temple , providing a fine view south to the Mediterranean and north to the C ? ? vennes mountains .
The Promenade du Peyrou was built in the 16th century .
