Place of inspiration for Caspar David Friedrich
Caspar David Friedrich was fascinated by the striking elevations of Bohemian Switzerland. He had often seen the landmarks from afar. In May 1808, he set off to finally draw some of them up close. During the hike, which lasted several days, he produced an interesting sketch showing Rosenberg and Kaltenberg from various distances. Immediately after his return, he processed his impressions in the painting "Bohemian Landscape". Both elevations also make prominent appearances in later works.
