The Queen's Well, which is located at an altitude of 529 m, is one of the strongest sources of streams Kraljevac (in the lower part of the flow is called Medvescak). Its name derives from the legendary Black Queen, probably Barbara of Celje, the second wife of King Sigismund, who had here her homestead in the first half of the 15th century. Before World War II Count of Kulmer Sestine built a hut, and beneath it a trout fish farm. The source has always been a popular resort of Zagreb. The water temperature in spring is 10 ° C. Close by is a restaurant, and access to the well is allowed through to the Educational trail Miroslavec that begins at "Šestinski lagvić."
