For the Geo Quiz, we are looking for a city in southern Germany. It is the capital of the state of Baden-WÃ¼rttemberg and the setting for a courtroom drama that got underway Tuesday.
German newspapers are calling it one of the most spectacular espionage trials since the end of the Cold War. A married couple identified only by their code names "Andreas Anschlag" and "Heidrun Anschlag" are accused of spying on NATO and the EU for decades.
When Heidrun was arrested, she was tapping out a coded radio message to Russia.
Stuttgart is the answer to the Geo Quiz.
It is here that a middle-aged couple is on trial on accusations of spying for the Russians for 25 years.
Anchor Marco Werman talks to JÃ¶rg Diehl, who is covering the trial for Der Spiegel Online.
