It is the connection between Leinestrasse u-Bahn and Tempelofer Feld. The park is wild and quiet, and super relaxing :) it is nice to sit on a bench and do some people-watching: it is a big inspiration for illustrators!
The Tempelhof Airport is now closed and they have transformed the landing field into a public park area. As soon as you go there you notice that usually you don't get to see that much sky in the city so entering this area for the first time is quite overwhelming. I especially love the old softball fields that have been built during the American occupation.
