Günzburg was founded in about 70 BC by the Romans to defend the borders of their land along the Danube; it was known as Castellum Guntia, Gontia or Contia.

[3] It consisted of a fort, later replaced by at least one other on the same site, a fairly large civilian settlement and most likely an important bridge over the Danube.

In 1301 the town became part of the Habsburg house and was developed into the centre of the Margraviate of Burgau; for a time (1803–1805) it was even the capital of all Further Austria.

She broke her journey towards France for two days and was joined by her father’s sister, Princess Anne Charlotte of Lorraine.

Günzburg has flourished, boasting a thriving downtown shopping area, scenic views of the nearby historic castle, and one of the top five Legoland theme parks in Germany.
