The Palais des Papes is one of the largest and most important medieval Gothic buildings in Europe. Once a fortress and palace, the papal residence was the seat of Western Christianity during the 14th century. Six papal conclaves were held in the Palais, leading to the elections of Benedict XII in 1334, Clement VI in 1342, Innocent VI in 1352, Urban V in 1362, Gregory XI in 1370 and Antipope Benedict XIII in 1394.
The palace construction began in AD 1252. 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.
The Palais is actually two joined buildings: the old palace of Benedict XII, which sits on the impregnable rock of Doms, and the new palace of Clement VI, the most extravagant of the Avignon popes. Together they form the largest Gothic building of the Middle Ages, it is also one of the best examples of the International Gothic architectural style. The construction design was the work of two of France’s best architects, Pierre Peysson and Jean du Louvres and the lavish ornamentation was the work of two of the best students of the School of Siena, Simone Martini and Matteo Giovanetti.
In addition, the papal library housed in the palace (the largest in Europe at the time with over 2,000 volumes), attracted a group of clerics passionate in the study, amongst the future founders of Humanism, Petrarch. At the same time, composers, singers and musicians were drawn to the Great Chapel. It was there that Clement VI appreciated the Mass of Notre-Dame de Guillaume de Machault, there that Philippe de Vitry at the pope’s invitation presented his Ars Nova and there that Johannes Ciconia came to study.
Due to its immense size, the Palais was also the place where the general organisation of the Church began to change. It facilitated the centralisation of services and the adaption of operations in order to suit the needs of the papacy, creating a truly central administration for the Church. The manpower of the Curia (Church administration), while 200 at the end of the 13th century, surpassed 300 at the beginning of the 14th century and reached 500 people in 1316. To this were added over 1,000 lay officials working within the palace.
Despite this, the Palais became obsolete when the papacy found it necessary to return to Rome. The hope of reuniting Latin and Orthodox Christians, along with the achievement of peace in the Papal States in Italy, made the case of returning stronger. Added to that was the strong conviction of both Urban V and Gregory XI that the seat of the papacy could only be the tomb of St Peter. Despite strong opposition from the Court of France and the College of Cardinals, both popes found the means to return to Rome, the first, on 30 April 1362, the second on 13 September 1370. This time, the return was absolute.
In the following centuries, the palace lost all of its former glory, despite it serving as the seat of two anti-popes and many cardinals. It retained, however, a “work of destruction” aspect that French poets and writers have referred to over the centuries, with its powerful sense of beauty, simplicity, grandeur and immortality.
Since 1995, the Palais des Papes has been classified, along with the historic center of Avignon, as a UNESCO World Heritage Site.References:
The Porta Nigra (Latin for black gate) is the largest Roman city gate north of the Alps. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. The name Porta Nigra originated in the Middle Ages due to the darkened colour of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as Porta.
The Porta Nigra was built in grey sandstone between 186 and 200 AD. The original gate consisted of two four-storied towers, projecting as near semicircles on the outer side. A narrow courtyard separated the two gate openings on either side. For unknown reasons, however, the construction of the gate remained unfinished. For example, the stones at the northern (outer) side of the gate were never abraded, and the protruding stones would have made it impossible to install movable gates. Nonetheless, the gate was used for several centuries until the end of the Roman era in Trier.
In Roman times, the Porta Nigra was part of a system of four city gates, one of which stood at each side of the roughly rectangular Roman city. The Porta Nigra guarded the northern entry to the Roman city, while the Porta Alba (White Gate) was built in the east, the Porta Media (Middle Gate) in the south, and the Porta Inclyta (Famous Gate) in the west, next to the Roman bridge across the Moselle. The gates stood at the ends of the two main streets of the Roman Trier, one of which led north-south and the other east-west. Of these gates, only the Porta Nigra still exists today.
In the early Middle Ages the Roman city gates were no longer used for their original function and their stones were taken and reused for other buildings. Also iron and lead braces were broken out of the walls of the Porta Nigra for reuse. Traces of this destruction are still clearly visible on the north side of the gate.
After 1028, the Greek monk Simeon lived as a hermit in the ruins of the Porta Nigra. After his death (1035) and sanctification, the Simeonstift monastery was built next to the Porta Nigra to honor him. Saving it from further destruction, the Porta Nigra was transformed into a church: The inner court of the gate was roofed and intermediate ceilings were inserted. The two middle storeys of the former gate were converted into church naves: the upper storey being for the monks and the lower storey for the general public. The ground floor with the large gates was sealed, and a large outside staircase was constructed alongside the south side (the town side) of the gate, up to the lower storey of the church. A small staircase led further up to the upper storey. The church rooms were accessible through former windows of the western tower of the Porta Nigra that were enlarged to become entrance doors (still visible today). The top floor of the western tower was used as church tower, the eastern tower was leveled, and an apse added at its east side. An additional gate - the much smaller Simeon Gate - was built adjacent to the East side of the Porta Nigra and served as a city gate in medieval times.
In 1802 Napoleon Bonaparte dissolved the church in the Porta Nigra and the monastery beside it, along with the vast majority of Trier"s numerous churches and monasteries. On his visit to Trier in 1804, Napoleon ordered that the Porta Nigra be converted back to its Roman form. Only the apse was kept; but the eastern tower was not rebuilt to its original height. Local legend has it that Napoleon originally wanted to completely tear down the church, but locals convinced him that the church had actually been a Gaulish festival hall before being turned into a church. Another version of the story is that they told him about its Roman origins, persuading him to convert the gate back to its original form.
In 1986 the Porta Nigra was designated a World Heritage Site, along with other Roman monuments in Trier and its surroundings. The modern appearance of the Porta Nigra goes back almost unchanged to the reconstruction ordered by Napoleon. At the south side of the Porta Nigra, remains of Roman columns line the last 100 m of the street leading to the gate. Positioned where they had stood in Roman times, they give a slight impression of the aspect of the original Roman street that was lined with colonnades. The Porta Nigra, including the upper floors, is open to visitors.
