Hammershus

Hammershus is a medieval era fortification at Hammeren on the northern tip of the Danish island of Bornholm.

[1] During a number of successive struggles between the kings of Denmark versus the Archbishopric, the fortress served as a refuge for the Archbishops including Bishop Jens Grand.

The rebels, led by Jens Pedersen Kofoed, shot the Swedish commandant Johan Printzenskiöld, and the Danish peasants traveled to Copenhagen to return the island to the king of Denmark.

Johann Conrad Dippel the German Pietist theologian, physician, alchemist and occultist were held imprisoned from 1719 to 1724 [6] at Hammershus.

Because of the unusual light on Bornholm, and because it has only four hours of darkness in summer, many of Denmark's earliest artists chose to paint views of Hammerhus.
