The Punkendeich was a dike (floodbank) between the river Weser and the city of Bremen that was known for prostitution. It ran from the city wall (Altenwall) to Sielwall. Originally called the Sieldeich, the Punkendeich was incorporated into the larger Osterdeich in 1850. A road and houses were built along the top of the dike, the road later becoming part of the Osterdeich trunk road.
