Kongsvinger is an ideal first stop for a road trip after landing in Oslo. Drive inland, and north. Save fjords for later.
The ancient Kongsvinger site looks over the Glama River valley, with Sweden close on the other side. The Norwegian side, whether or not formal boundaries among Nordic groups emerged then or later, needed defenses.
Who was in charge when? Reconciling dates of early kings with activity at Kongsvinger is difficult. The museum at Kongsvinger cites Harald the Hard, Harald Hardrada, Harald the Hard Ruler, with tumult in the late 800's, according to a medieval recorder of histories, Snorre Sturlassen, see http://www.kvinnemuseet.no/?q=node/52/.
Harald Hardrada, however, is cited eas the same as Haraldr Siguroarson who ruled in 1046-1066 as Harald III, see http://en.wikipedia.org/wiki/Harald_Hardrada/. Keep the Haralds straight as delving continues in Scandinavian history. There are many. Our American schooling ignored Scandinavia except to gloat about "Christian" militants taking over, as though there was no worth to what there was before Ignore the dogmatic clerical sirens.
By the seventeenth century, Swedish-side incursions had increased; and with the assistace of Scots mercenaries, and even nobles in search of vaster influence. See Kvam and Otta sites here.
Kongsvinger Fortress, bad baby room.
Upon closer inspection of the Norwegian information about this little door in the wall at an apparently officers' quarters,we concluded that the bad babies must have been kept elsewhere. This was the hunderie, the place of the hounds, the doggies for the hunts in whatever Norwegian Wood.
Fortress doors. See the clever littler door for one, when one dare not ope the big one. Knock knock.
Or were they only for torch-lamps? And the little door there to the right. Where does it lead? Surely, not for a guard because a guardhouse would have a sliding window to see who's there.
