Red flag with a white stylized castle featuring three towers and a central gate, taken from Hamburg’s coat of arms.
The flag of Hamburg uses a red field with the city’s castle emblem derived from its coat of arms. The red background reflects Hamburg’s historic association with the Hanseatic League, while the white castle symbolizes the city’s fortified character and its status as a free imperial city. The three towers are traditionally linked to Hamburg’s historic gates or districts. The emblem is rooted in a seal recorded in 1241. The civil flag was adopted in 1834, while a separate state flag with the greater coat of arms was introduced in 1897.
