Bay of Kiel
Eckernförde Bay (; ) is a firth and a branch of the Bay of Kiel between the Danish Wahld peninsula in the south and the Schwansen peninsula in the north in the Baltic Sea off the lands of Schleswig-Holstein, Germany. The bay extends around deep into the land and is wide at its entrance where "Booknis-Eck" (municipality of "Waabs") and "Danish-Nienhof" (municipality of "Schwedeneck") mark the endpoints. The bay is up to deep. The border to the Kiel Fjord lies at the Bülk Lighthouse. The once forested Danish Wahld peninsula between Kiel Fjord and Eckernförde Bay constituted the borderland between the Saxons and the Danes until the Middle Ages. At the inner end of the bay lies the town of Eckernförde.
