Signhildsberg

Signhildsberg is a manor that formerly was a royal estate, 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.

Etymology

The name Sigtuna is contested. According to one theory, it is a compound name where the second element is -tuna and the first one is either of two closely related dialectal words, viz. sig meaning "seeping water" or "swamp" or sik meaning "swamp". As a basis for this intpretation, a brook south of Signhildsberg has been mentioned, or the fact that the estate was surrounded by marshy terrain.
Another theory considers the name to be an ancient prestigious "wander toponym", meaning "strong fortress", like the Celtic toponym Segodunum, from Proto-Germanic *sigatūna-, Old Norse Sigtún, cf. Proto-Germanic *segaz ~ *sigiz- "victory": Gothic sigis, Old Norse sigr, Old English sigor, Old Frisian sige, sīge, Old High German sigi, sigu.
In 1680, the name was changed to Signhildsberg after the Old Norse legend of Hagbard and Signy.

writes in Book 8 of Gesta Danorum that Sigmund, one of the warriors of the House of Yngling, came from what is chronologically Old Sigtuna to fight at the Battle of Bråvalla:

Archaeology

There are two large ruins that had been two large three-aisled halls, a series of terraces just above the shore-line of the Germanic Iron Age, traces of a harbour, a large mound and a number of smaller grave fields. Excavations have dated the remains to the Vendel Age, part of the Germanic Iron Age, and the Viking Age, i.e., from the 6th century until the 11th century.

History

It was an Iron Age and mediaeval royal estate and it was located strategically at the waterway to Old Uppsala and the Temple at Uppsala. In the 10th century, the name was transferred to modern Sigtuna, which apparently assumed many of its functions.

It is mentioned in the 1170s when Pope Alexander III addresses king Knut Eriksson and Jarl Birger Brosa. The pope demands that they return to the archbishop of Uppsala the villages Strom, Fornesitune and Guazbro. The villages had earlier belonged to the bishop of Sigtuna, but they had been confiscated by the crown when the bishopric had been moved to Gamla Uppsala.
In 1299, Birger, [King of Sweden|Birger Magnusson], the son of Magnus Ladulås, spent some time in Old Sigtuna as one of his letters was written in Sightonia Antiqua or apud antiquam Sightoniam The difference seems to be a matter of presenting the name in the nominal case or preserving the case in which the name appeared in the original text.
In 1315, according to Svenskt Diplomatarium III nr 2032 , Duke Erik Magnusson was bestowed a part of Old Sigtuna, which is called Siktonia vetus. Neighbouring properties are also named: Norgungi and Frötunum
In 1541, according to Kammar-ark.: jordeböcker, Uppland 1541 nr 5, the location is named as one of Gustav I Vasa's estates and spelled Forsictuna, Foorsictuna and Fforssiiktwna.
In 1542, according to Gustav Vasas jordebok are mentioned Foorsictuna and Norringe
In 1551, according to Sven Nielssons jordebok för Stäkets län, it is mentioned as the royal estate of Forsictuna.
In 1567, it is mentioned as Foder Sictuna in the province of Uppland
In the 17th century, the name Försigtuna is used on a map.

Since the 17th century, the location has been a manor named Signhildsberg or Signesberg.
