Ruins
Hammershus Slotsruin
The impressive ruins of Hammershus Slot, dramatically perched on top of a cliff 74m above the sea, are the largest in Scandinavia. The castle was thought to have been built in the early 1300s, and a walk through the evocative site, enjoying the views, is a must for Bornholm visitors. The grounds are always open and admission is free. A smart new visitor centre is being built, sympathetic to the surrounds (opening 2018; likely with an admission fee for exhibits).
