Basel-Münsterhügel
Basel-Münsterhügel is the site of an Iron Age  (late La Tène) fort  or oppidum, known as Basel oppidum, constructed by the Gaulish Rauraci after the battle of Bibracte in 58 BC. It  the site of  Basel Minster, in the Swiss city of Basel.The fort was abandoned or destroyed shortly after its construction, before the end of the 1st century BC, with the Roman conquest of the Alps and the establishment of the province of Gallia Belgica. By the early 1st century AD, there was a small vicus on the hill built on top of the ruins of the oppidum, possibly the origin of the name Basilia, from a toponym villa Basilia "estate of Basilius". In the mid-3rd century, the ruined oppidum was rebuilt as a Roman castrum, fortified with an encircling wall in c. 270. The vicus was abandoned, and the hill served as part of the Roman fortifications of the Rhine against the advancing Alamanni throughout the 4th century.
