'Obernburg am Main' (official: Obernburg a.Main) is a town in the
district of Miltenberg,
Bavaria,
Germany.
History
Between
83 and
85 AD the Obernburg Fort was founded by
Romans.
It was the garrison of the Cohors IIII Aquitanorum equitata, and possibly also at the same time of the Numerus Brittonum et exploratorum Nemaningensium. The stone fort, with an area of 2.9 ha and a nearly rectangular ground plan of c. 185/188 x 160 m was oriented to the river
Main. A beneficiarii station has been demonstrated on the Limes road south of the fort, from which numerous dedication stones have been secured and are to be exhibited in a newly established museum.
During the invasion of the
Alamanni 259/
260 AD the fort was destroyed. Fort and vicus grounds were densely built over by the mediaeval town centre.
On
March 25 1313 the
Archbishop of Mainz Peter von Aspelt made the village to a city.
Until the
German Mediatisation in
1803 Obernburg had belonged to the
Archbishopric of Mainz
After this it was a part of the new founded
Principality of
Aschaffenburg, which
1810 became a part of the
Grand Duchy of
Frankfurt. In
1814 it finally became a part of
Bavaria. On
July 1 1972 Obernburg lost its position as a district capital. An
Amalgamation on
May 1 1978 made
Eisenbach a
Neighbourhood of Obernburg.
