Junkarsborg was a medieval castle in Raasepori. There are no documents left of castle, but archaeologists suppose that the castle was built in the early 14th century and was used until the beginning of the 15th century. Iron and bronze items, ceramics and silver coins have been found from the castle site. Remains refers to Rheinland in Germany and one theory believes that the castle was originally built by the Danish soldiers.
Nowadays there are only rectangular earth walls left. The ruins are on a forested island in the middle of the Svartå river and can only be reached on foot. Some reconstruction work has been done during 2005-2006 to improve the access to the island and its visual appearance.
