Pottery, which is typical for the 2nd half of the 9th century, was found in the settlement layer of the time after the Viking attack. In addition to local pottery, pots from Frisia and Slavic regions were found as well. Slavic pottery is decorated with patterns that have either been carved or pressed with a stamp. Some local potscopy the Slavic way of decoration. In addition, a rare lamp shell was discovered. Filled with oil, grease or blubber-oil it illuminated the houses in Hammaburg.
