Ruins
If you are interested in looking at ruins – castle ruins or church ruins – then this opportunity is present on Bornholm. You can see 2 church ruins and four visible castle ruins, the most famous of which is Hammershus, also the largest castle ruin in northern Europe.
There are supposedly 3 more ruins on the island, but here no masonry or other visible evidence is found, but because of the area’s appearance or location it is believed that there once was a castle.
