I-Spy Vienna. The Russian War Memorial

One of Stalin's priorities at the end of World War Two was to get Soviet war memorials erected sharpish in what would become Western European countries. One went up in 1945 just inside what became West Berlin by the Tiergarten just inside the Brandenburg Gate. 

The one in central Vienna also went up in 1945 within months of the end of the war. Locals refer to it rather unkindly as the 'Monument to the Unknown Looter'. The memorials gave the Russians a useful foothold in the West, with guards stationed by the one in Berlin, while Putin was a regular visitor to Vienna's. If he goes back now, he'll find the huge wall at the back has been painted in the colours of Ukraine.
