The Bischofshof Brewery was founded in 1649 near the famous Cathedral of Regenburg by Bishop Wilhelm Graf von Wartenberg; although historians have evidence that a brewery for the Bishops already existed in 1280 AD, and actually had been providing beer during the construction of the Regensburger Cathedral from 1280 to 1520. Today the Brewery is still owned by the Diocese, and combines tradition with the latest brewing technology.
