Hammaburg

9th century · 9th century

The Hammaburg was a fortification built in the early 9th century near the meeting of the Alster and the Elbe, from which Hamburg takes its name. Probably founded under Charlemagne or Louis the Pious to secure the Frankish frontier in Saxony, it became the seat of Archbishop Ansgar's mission to Scandinavia. Vikings sacked it in 845.
