La Défense is Europe’s largest business district, with 2,500 businesses and 180,000 employees spread among 71 towers. Built in the 1960s, the area is easily visible due to its high-rise buildings. It is also home to the Quatre Temps shopping centre, which covers over 160 hectares and is divided into four large sections (North Arch, South Arch, North Esplanade and South Esplanade).
