It is 30 years since the tumultuous events of 1989, when the Berlin Wall fell, the Iron Curtain lifted and the Soviet Empire began to crumble.

As part of a special series of reports on how Russia views 1989, BBC Moscow correspondent Steve Rosenberg has travelled to former East Germany.

He took a look inside Wünsdorf, a complex near Berlin that housed tens of thousands of Soviet troops.
