Another important timber-frame building is the old "Amt" apothecary’s shop, whose foundations go back to 1330, and which was newly built in 1492 as a "Burgmannenhaus" for the Hattsteins. From 1663 the house harboured an apothecary’s shop. Today’s "Guttenberger Hof" was first mentioned in 1336 as the family von Hattstein’s seat. It was overhauled and built into its current form in 1526. In 1767 ownership passed to the family von Guttenberg and in 1820 to common (that is to say, not noble) ownership. As of October 2007, the "Guttenberger Hof" is being restored.
