Palais des Papes, Avignon, France
The Palais des Papes (lo Palais dei Papas in Occitan) is a historical palace in Avignon, southern France, one of the largest and most important medieval Gothic buildings in Europe. Avignon became the residence of the Popes in 1309, when the Gascon Bertrand de Goth, as Pope Clement V, unwilling to face the violent chaos of Rome after his election (1305), moved the Papal Curia to Avignon, a period known as the Avignon Papacy. Clement lived as a guest in the Dominican monastery at Avignon, and his successor Pope John XXII set up a magnificent establishment there, but the reconstruction of the old bishops' palace was begun in earnest by Pope Benedict XII (1334–42) and continued by his successors to 1364. The site, on a natural rocky outcrop at the northern edge of Avignon, overlooking the river Rhône, was that of the old episcopal palace of the bishops of Avignon. The Palais was built in two principal phases with two distinct segments, known as the Palais Vieux (Old Palace) and Palais Neuf (New Palace). By the time of its completion, it occupied an area of 11,000 m² (2.6 acres). The building was enormously expensive, consuming much of the papacy's income during its construction.
The Palais Vieux was constructed by the architect Pierre Poisson of Mirepoix at the instruction of Pope Benedict XII. The austere Benedict had the original episcopal palace razed and replaced with a much larger building centred on a cloister, heavily fortified against attackers. Its four wings are flanked with high towers.
Under Popes Clement VI, Innocent VI and Urban V, the building was expanded to form what is now known as the Palais Neuf. Jean de Louvres was commissioned by Clement VI to build a new tower and adjoining buildings, including a 52 m long Grand Chapel to serve as the location for papal acts of worship. Two more towers were built under Innocent VI. Urban V completed the main courtyard (known as the Court d'Honneur) with further buildings enclosing it. The interior of the building was sumptuously decorated with frescos, tapestries, paintings, sculptures and wooden ceilings. Since 1995, the palais des Papes has been classified along with the historic center of Avignon, as a UNESCO World Heritage Site, under cultural criteria i, ii and iv.
