It ran from the city wall (Altenwall) to Sielwall (today's Deichstraße to Siel am Dobben).

[3] The name probably dates from the Seven Years' War (1756-1763), when the soldiers' prostitutes - the so-called Punken - were not tolerated within Bremen itself and set up on the dike outside the city wall.

[4] Every year on 6 January, the Bremer Eiswette (Bremen Ice Bet), a local folk festival whose history dates back to 1829, takes place on the former Punkendeich.

The "President of the Ice Bet", assisted by Novices and Pages,[10] oversees proceedings, and the Notarius publicus, complete with legal wig, ensures fair play.
