Basel

The name of Basel is first recorded as Basilia in the 3rd century (237/238), at the time referring to the Roman castle. This name is mostly interpreted as deriving from the personal name Basilius, from a toponym villa Basilia ("estate of Basilius") or similar. Another suggestion derives it from a name Basilia attested in northern France as a development of basilica, the term for a public or church building (as in Bazeilles), but all of these names reference early church buildings of the 4th or 5th century and cannot be adduced for the 3rd century attestation of Basilia. By popular etymology, or simple assonance, the basilisk becomes closely associated with the city, used as heraldic supporter from 1448, represented on coins minted by the city, and frequently found in ornaments. …

There are traces of a settlement at the nearby Rhine knee from the early La Tène period (5th century BC). In the 2nd century BC, there was a village of the Raurici at the site of Basel-Gasfabrik (to the northwest of the Old City, and likely identical with the town of Arialbinnum that was mentioned on the Tabula Peutingeriana). The unfortified settlement was abandoned in the 1st century BC in favour of an oppidum on the site of Basel Minster, probably in reaction to the Roman invasion of Gaul. In Roman Gaul, Augusta Raurica was established some 20 km (12 mi) from Basel as the regional administrative centre, while a castrum (fortified camp) was built on the site of the Celtic oppidum. In AD 83, the area was incorporated into the Roman province of Germania Superior. The Roman Senator Munatius Plancus is known as the traditional founder of Basel since the Renaissance. …
