At his death, Gero's march extended as far as the Neisse river. He was not popular with the Saxon nobility of his day, because he had a strong sense of moral rectitude and was of low birth. Nonetheless, he became celebrated in the "Nibelungenlied" as the "marcgrâve Gêre", though it has been disputed whether he was ever officially accorded that title. Gero's tomb can still be see in Gernrode today. A decorative painting was added to it c. 1350. It depicts Gero standing over a vanquished Wend.
