Bornholm’s sights are unique. Whether you visit the rocky Sanctuary Cliffs at Helligdommen, Northern Europes largest castle ruin Hammershus or the white round churches from the 12th century – you can choose your favorite. Many of theses places are open all year round.
See the medieval fortress, where even the Lords Templar are said to have been. In the Round Church in Østerlars you can walk up to the upper levels and enjoy the view from the old loopholes.
Follow the sign to the spot, where you have the best echo in the valley - and then shout from the bottom of your heart (or lungs). In order to test the valley - you'll hear many Danes shouting "Hvad drikker Møller? - Øller" (What drinks Miller? - Beers).
After completing the mandatory fitness programm (walking down the long stair and up again afterwards) to get down to the rocky cliff that looks like a church, you are rewarded with a breathtaking view into a cave, where Jon the Preacher is said to have lived.
