Dalaborg
Dalaborg was a castle on the western shore of Lake Vänern in Dalsland, north of the mouth of the Dalbergsån. Dukes Erik and Valdemar, sons of King Magnus Ladulås, built it in 1304. Its position made it a meeting place in the struggle for Sweden's crown: here in 1388 Margaret, already regent of Denmark and Norway, was recognised as regent of Sweden. The fortress was destroyed in 1434 during the rebellion of Engelbrekt against Eric of Pomerania.
