There seems to be a lot of construction in Copenhagen involved with improving/expanding the metro. Near the Amalienborg Palaces is a construction fence around the side of the nearby church. Perhaps it has been adopted by an art school?
There were a series of foam panels covering the fence with a depiction of a colonnade or aqueduct with pictures in each of the arches. All were in a classical style, but some had modern anachronisms, such as the flying saucer in this idyllic scene. Another had a harbor scene with sailing ships and a helicopter and submarine added.
