Unsure if this is the connection, but the guy who discovered Troy in the late 1800's (Heinrich Schliemann) actually brought Troy artifacts to a Berlin museum, which someone with more knowledge of Berlin than me may be able to draw more connections from.
Per his Wikipedia:
"In 1874 Schliemann published Troy and Its Remains. Schliemann at first offered his collections, which included Priam's Gold, to the Greek government, then the French, and finally the Russians. In 1881, his collections ended up in Berlin, housed first in the Ethnographic Museum, and then the Museum for Pre- and Early History, until the start of WWII.
In 1939, all exhibits were packed and stored in the museum basement, then moved to the Prussian State Bank vault in January 1941. In 1941, the treasure was moved to the Flakturm located at the Berlin Zoological Garden, called the Zoo Tower. Dr. Wilhelm Unverzagt protected the three crates containing the Trojan gold when the Battle of Berlin commenced, right up until SMERSH forces took control of the tower on 1 May.
On 26 May 1945, Soviet forces, led by Lt. Gen. Nikolai Antipenko, Andre Konstantinov, deputy head of the Arts Committee, Viktor Lazarev, and Serafim Druzhinin, took the three crates away on trucks. The crates were then flown to Moscow on 30 June 1945, and taken to the Pushkin Museum ten days later. In 1994, the museum admitted the collection was in their possession."
