Ragnhildsholmen, Medieval castle ruins on an islet near Gothenburg, Sweden.
The stone remnants of Ragnhildsholmen castle stand on a hill, featuring a square courtyard with walls and a tower on the eastern side.
Norwegian King Håkon Håkonsson constructed this border fortress around 1250 AD to protect the southeastern territory and the city of Kungahälla.
Archaeological excavations in 1881 revealed a collection of medieval artifacts including coins, weapons, household items, and tools from daily castle life.
Visitors can access the ruins by following Kongahällavägen road toward Säve, where directional signs lead to a designated parking area.
The castle site now functions as a bird sanctuary, hosting nightingales, warblers, and harriers among the ancient stone structures.
