Signhildsberg (historically Fornsigtuna, where forn means ancient, Old Sigtuna, Sithun, Signesberg) is a manor that formerly was a royal estate (Uppsala öd), located in the parish of Håtuna approximately west of the modern town of Sigtuna, by Lake Mälaren in Sweden. Although the location is nearly forgotten, it has a central role in Norse mythology, according to which it was founded by the Norse god Odin.
