I decided to visit here because of the recommendation from an article in Süddeutsche Zeitung.
It is a very special place, a well-kept ruin of an old airport.
Now it is an open public park.
People can grill barbecues, ride bikes, rollerskates, or just walk around.
I could totally be relaxed here, because there were nothing here but an open ground.
I would like to recommend visiting this place to anyone who needs a peace of mind.
You can arrive here by taking a short walk from the Tempelhof S-bahn and U-bahn station.
