context_page_description: Trier, formerly known in English as Treves and Triers, is a city on the banks of the Moselle in Germany. It lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region.
  Founded by the Celts in the late 4th century BC as Treuorum and conquered 300 years later by the Romans, who renamed it Augusta Treverorum, Trier is considered Germany's oldest city. It is also the oldest seat of a bishop north of the Alps. In the Middle Ages, the archbishop-elector of Trier was an important prince of the Church who controlled land from the French border to the Rhine. The archbishop-elector of Trier also had great significance as one of the seven electors of the Holy Roman Empire.
  With an approximate population of 105,000, Trier is the fourth-largest city in its state, after Mainz, Ludwigshafen, and Koblenz. The nearest major cities are Luxembourg, Saarbrücken, and Koblenz.
context_section_description: Trier is known for its well-preserved Roman and medieval buildings, which include:
  the Porta Nigra, the best-preserved Roman city gate north of the Alps;
  the huge Constantine Basilica, a basilica in the original Roman sense, was the 67 m (219.82 ft) long throne hall of Roman Emperor Constantine; it is today used as a Protestant church; adjacent is the Electoral Palace, Trier;
  the Roman Trier Amphitheater;
  the 2nd century AD Roman bridge (Römerbrücke) across the Moselle, the oldest bridge north of the Alps still crossed by traffic;
  ruins of three Roman baths, among them the largest Roman baths north of the Alps; including the Barbara Baths and the Trier Imperial Baths;
  Trier Cathedral (German: Trierer Dom or Dom St. Peter), a Catholic church that dates back to Roman times; its Romanesque west façade with an extra apse and four towers is imposing and has been copied repeatedly; the Cathedral is home to the Holy Tunic, a garment said to be the robe Jesus was wearing when he died, as well as many other relics and reliquaries in the Cathedral Treasury;
  the Liebfrauenkirche (German for Church of Our Lady), which is one of the most important early Gothic churches in Germany, in some ways comparable to the architectural tradition of the French Gothic cathedrals;
  St. Matthias' Abbey (Abtei St. Matthias), a still-in-use monastery in whose medieval church the only apostle north of the Alps is held to be buried;
  St. Gangolf's church is the city's 'own' church near the main market square (as opposed to the Cathedral, the bishop's church); largely Gothic;
  Saint Paulinus' Church, one of the most important Baroque churches in Rhineland-Palatinate and designed in part by the architect Balthasar Neumann;
  two old treadwheel cranes, one being the Gothic "Old Crane" (Alte Krahnen) or "Trier Moselle Crane" (Trierer Moselkrahn) from 1413, and the other the 1774 Baroque crane called the  "(Old) Customs Crane" ((Alter) Zollkran) or "Younger Moselle Crane" (Jüngerer Moselkran) (see List of historical harbour cranes).
