The manhole covers in Rostock display the city arms. The coat of arms dating back to 1367 depicts a golden griffin of a blue field (representing the former princes of Rostock) with bars of silver and red (the colours of the Hanseatic League). As a member of the Hanseatic League the city is named Hansestadt Rostock. [German]
