Hamburger Kunsthalle
Altstadt / Glockengießerwall, Germany
The Kunsthalle brings together centuries of European art in three contrasting buildings near the main station and Alster. Its collections range from Old Masters to contemporary work, with German Romantic painting a particular strength. Caspar David Friedrich and Philipp Otto Runge sit within a broader story that also includes Impressionism and modern art. Choose a few sections that interest you rather than trying to see everything, and check the temporary exhibitions before deciding how much time to allow.
