Home to a giant Nazi-built terminal building and scene of the famous Berlin Airlift in 1948 when Allied planes flew in much-need supplies to war-weary West Berliners during the Cold War, Templehof Airport’s 950-acre system of old runways and grassy expanses (larger than New York’s Central Park) opened as a public park in 2010. Rollerbladers, picnickers, joggers, kite-flyers and people out for a stroll now flock there (an estimated 50,000 per weekend) for a taste of the urban outdoors.
