The legend fountain at the "Alten Markt" was designed and built in 1995 by Bonifatius Stirnberg from Aachen. The fountain shows figures from five regionally known legends. You can see Miss Maria von Jever, who according to legend did not die but disappeared through an underground passage near Jever Castle and is said to return at some point. Another group of figures shows Count Anton-Günter von Oldenburg with his dapple grey horse "Kranich". The count's favourite horse is said to have saved his life when thick fog came up during a ride to the island of Wangerooge and the count lost his bearings. Despite the dangerously rising tide, the horse brought the count safely back to the mainland. The large, white Scheeper Hare is said to have pushed farmers who were not quite sober into the ditch. The witch ship shows two witches from the neighbouring Butjadinger Land who, according to legend, caused mischief among the fishermen of the Jeverland using a milk sieve as a boat and cow ribs as oars. The Gudrun saga from the 9th century tells of the Danish singer Horand, who rode on the sand towards “Givers”. This is supposedly the first mention of Jever.
