The place was conveniently located on an old road that was built during the Carolingian period and led from Roßtal to Höfstetten.[5] In 1300, the place was first mentioned in a document as "Gaulenhouen" in the land register of the Bishopric of Eichstätt. The place name is derived from the personal name of the founder, Gulo.[6] At that time, the place was largely deserted. One property was under the control of the Lords of Heideck, which was later enfeoffed to Nuremberg patricians. In 1407, only one farm was recorded, which was under the control of the Eichstätt Treasury Office of Abenberg.[7] In 1671, there were 5 properties in Gaulnhofen, one of which was under the control of the Treasury Office of Abenberg and four of which were under the control of the Imperial City of Nuremberg.[8] In 1732, according to the Oberamt descriptions by Johann Georg Vetter, there were still 5 properties in Gaulnhofen, of which 2 properties were under the jurisdiction of the Schwabach Treasury Office, 1 property under the Abenberg Treasury Office and 2 properties under the State Alms Office of the Imperial City of Nuremberg.[9]
Towards the end of the 18th century, there were 5 properties and a community shepherd's house in Gaulnhofen. The high court was administered by the Brandenburg-Ansbach Oberamt Schwabach. The village and community authority was held by the Schwabach Treasury Office. The landlords were the Schwabach Treasury Office (1 half farm, 1 Köblergut), the Eichstätt Treasury Office Abenberg (1 whole farm), the State Alms Office of the Imperial City of Nuremberg (1 whole farm) and the Nuremberg owner von Grundherr (1 three-quarter farm).[10]
From 1797 to 1808, the place was under the jurisdiction of the Schwabach Justice and Chamber Office. As part of the municipal edict in 1808, Gaulnhofen was assigned to the Rohr tax district (Section II) and the Prünst rural community, which was formed in 1818. On May 1, 1978, Gaulnhofen was incorporated into Rohr as part of the regional reform in Bavaria.
