Entrevaux (; ) is a commune (municipality), former episcopal seat (not bishopric in title, that remained the Diocese of Glandèves) and Latin Catholic titular see in the Alpes-de-Haute-Provence department in southeastern France. Geography Set on both sides of the narrow road between Annot and Puget-Théniers that runs alongside the gorge of the river Var, the medieval walled town lies in the shadow of a mountaintop citadel. History Following incursions of Saracens and the razing of the old town of Glandèves, which became a bishopric no later than the sixth century, the more defensible site of medieval Entrevaux was founded in the 11th century on the rocky spur in an angle of the river; the oldest recorded name is Interrivos and dates from 1040. Between 1481 and 1487, Provence became a part of France. In 1536, Entrevaux fell to the troops of Charles V, Holy Roman Emperor, betrayed by its lord Jacques Glandeves; half the population was massacred (coll.). The remaining population staged an uprising, cutting the throat of the governor, and offered the town to the French Dauphin, King François I. In recognition of this, Entrevaux was given the Municipal charter (city law model) of Avignon and declared a royal town of France, with its inhabitants exempt from taxation. In the 16th century, the bishop's official seat at the Glandèves Cathedral in Glandèves was abandoned, and a new one, Entrevaux Cathedral, was constructed in Entrevaux though still the seat of the Bishop of Glandèves. It served as a cathedral until 1790, but the see persisted until 1801. In 1658 a bridge guarded by towers and a portcullis was constructed over the Var; this is the modern Porte Royale. In 1690 the military architect Vauban drew up plans to further fortify the town, due to its strategic position guarding the valley of the Var and on the border with Savoy. Although not completed in full, the citadel perched high above the town was strengthened, particularly on the more accessible side closest to the hilltops, and a protected walkway constructed up the side of the mountain from the town. Two small forts were provided to protect the town, and its two main gates—now called the and the —strengthened. Entrevaux was briefly besieged in June 1707 by the royalist Savoyards under Chevalier Blaignac, but resisted and was relieved by the French forces. The citadel was last used during World War I as a
