Great fire of Hamburg The Great fire of Hamburg began early on May 5, 1842 in Deichstraße and burned until the morning of May 8, destroying about one third of the buildings in the Altstadt. 51 people were killed and 1,700 residences and several important public buildings were destroyed. The fire required major rebuilding of the city and led to improvements in its infrastructure. The heavy demand on insurance companies also led to the establishment of reinsurance.
