To see one of the city’s best examples of communist “art”, and one of the least noticed, head to Moscow Station, go to the main entrance hall and look up. The colourful ceiling mosaic makes you feel as if you are lying on your back in a sunlit square, looking at the sky. Its unique perspective makes it one of the more original and less austere examples of communist propaganda. It suggests unity and celebration; happier times that perhaps never came. The Olympic flags tell you it’s from the fifties, when the Soviet Union joined the Olympic family.
