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.

The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
