The Architecture of Provence includes a rich collection of monuments from the Roman Empire; Cistercian monasteries from the Romanesque Period, medieval palaces and churches; fortifications from the time of Louis XIV, as well as numerous hilltop villages and fine churches. Provence was a very poor region after the 18th century, but in the 20th century it had an economic revival and became the site of one of the most influential buildings of the 20th century, the Unité d'Habitation of the architect Le Corbusier in Marseille.
Provence in the southeast corner of France, is generally defined as the French Departments of Var, Bouches-du-Rhône, Vaucluse, and part of Alpes-de-Haute-Provence and Alpes-Maritimes. The original comté de Provence extended from the west bank of the Rhone River to the east bank of the Var river, bordering the comté of Nice. Provence culturally and historically extended further west of the Gard to Nîmes and to the Vidourle river.
