In 1075, Hugo de Hachenfels sold his lands in Olkenbach to Saint Simeon's Monastery at Trier for 260 silver marks in a deed documented by Archbishop of Trier Udo. The Lords of Hachenfels are said to be the village's namesake. In 1112, Cuno de Hachenfels cropped up in a document about an exchange of holdings between Disibodenberg Monastery and Provost Richard von Liebfrauen in Mainz. Named as an occupant of the Hachenburg (an old castle near the Hachenfels) in 1128 was Adalbero de Hachenfels, who also cropped up in a donation document from Archbishop of Mainz Adalbert I to Disibodenberg Monastery. In 1140, Emicho VI's two sons formed the lines of the Waldgraves and Rhinegraves (Konrad) and the Raugraves (Emich VII). It was in this time that a new castle, the Naumburg, was built near Bärenbach, within whose domain lay Schmidthachenbach. In 1172, Emich VII transferred ownership of the Naumburg to his brother Gerlach. In 1323, Raugrave Conrad sold Archbishop of Trier Baldwin the Naumburg for 1200 "Heller", whereupon Baldwin enfeoffed Conrad with the very castle that he had just sold.
