The brewery is located in the former Palais Pfeiff, a baroque palace that was built from 1722/1723. It was built by the Kurmainzischer Hofkammerrat and resident Adam Anton Pfeiff (* around 1690; † 1748), who bought three houses with very unfair means and converted them into this palace. Pfeiff made a fortune, not necessarily always by legal means, from the possession of the three large Oberursel copper hammers. He quickly brought the entire production and trade under his control and was not very squeamish about it. After Pfeiff moved from Oberursel to Frankfurt shortly after completion of the house, where he died impoverished, it passed on to his son-in-law, the Mainz court secretary Chiochetti. The next owner, the Oberurseler J.A. Ochs, opened an inn here, which it still operates under various names - Zum Römischen Kaiser (1810–1873), Zum Deutschen Kaiser (1873–1918), Zum Deutschen Haus (1918–1993) and Alt-Oberurseler Brauhaus (since 1994 ) - has stayed.
In the 1990s, considerable construction defects were found, so that in 1999 extensive renovation work began on the outside area, after which the interior spaces were restored.
The stairwell, the stucco ceilings and the "flower room" are remarkable. If you like, you can get married in this prestigious setting, because the brewery acts as a branch of the registry office, as the city of Oberursel contributed to the renovation costs.
