Despite the cold, wet weather, up to 500 protesters gathered outside Tempelhof to vent their anger at the closure of the airport.
It was a last show of strength by campaigners who had fought a series of legal battles over the past decade to save Tempelhof.
Holding candles, they didn't seem too bothered by the cold or the police.
One man screamed, "If the Mayor of Berlin, Klaus Wowereit, has guts, then tell him to come out here."
The protesters say they won't give up.
"We still have a couple of legal challenges pending," said Rainer Classe, a campaigner. "We're also trying to get Tempelhof listed as a Unesco World Heritage site - the airport would finally get the recognition that it deserves."
Inside the massive terminal, the authorities had thrown a big party as a send-off for Tempelhof. The local TV channel RBB set up a large stage and the whole event was broadcast live.
But as hundreds of local VIPs, the mayor of Berlin and officials popped open the champagne bottles, it seemed odd that they were celebrating the closure of the airport.
