The Tungri came to dominate this area, and are the reason for the name of the modern name Tongeren, coming from the ancient "Tungrorum" meaning "of the Tungri". Tacitus says that Tungri was a new name for the original tribes who had previously been called the Germani. But many modern writers believe that the Gallo-Roman population of the area contained a significant amount of more recent Germanic immigrants from across the Rhine. Located on the important road linking Cologne to Bavay via the relay of Liberchies, and surrounded by the fertile lands of the Hesbaye region, Roman Tongeren quickly became one of the largest Gallo-Roman administrative and military towns in the 1st century. It suffered from a destructive fire during the Batavian siege in 70CE, which was part of the Batavian revolt. In the 2nd century, it erected a defensive wall, portions of which can still be seen today. Typical Roman buildings were built in town, while villas and mound graves (tumuli) dotted the surrounding area.
Middle Ages
In the 4th century, the city became the center of a Christian diocese � one of the earliest in the Low Countries � under the influence of Saint Servatius, bishop of Tongeren, who died in 384CE. The seat of the Tungrian bishopric however eventually moved to nearby Li�ge, possibly with a period in Maastricht. Aduatuca Tungrorum may have been destroyed by the Huns in 451CE. Tongeren therefore lost some importance during this period.
Waves of Germanic settlers and invaders changed the area significantly. The Merovingian period between the 5th and the 8th century is not well documented. The building of a new church and the foundation of a chapter of canons took place in Carolingian times, at the very place where the old bishops� houses stood, and where the basilica still stands today. The construction of the current basilica started at the beginning of the 13th century in the prevalent Gothic style of that period. Other buildings were
