Went out to find good spots for photo sessions, and this medieval fort ruin, called Ragnhildsholmen, was great.
Ragnhildsholmen belong to Norway around 1250’s when it was built. Sweden won over the whole region in 1658 in The Roskilde Peace Treaty negotiations. This fort however, was only in use for about hundred years as its significance was replaced by the bigger and better located Bohus fästning (which was sieged fourteen times but never overtaken).
The hill on where the fort once stood intact was surrounded by water as the water level was 2 m higher than today.
