How about a history lesson with your trip to the park? Though perhaps not on the same gob-smacking par as the Soviet Memorial at Treptower Park, this leafy retreat just near Tempelhof Airport possesses the Hill of the Cross, whose German translation is also the moniker of the district Kreuzberg. The cross-bearing monument atop the hill was built as a memorial of the Wars of Liberation in the early 19th century.
Follow the path beyond the monument and step into a man-made oasis. The waterfall that tumbles over the rocks, though artificial, is nonetheless stunning and a tranquil escape in landlocked Berlin.
