The city was Edinburgh and it caused quite a stir, as you might imagine.

Dr D P Thomson brought things down to earth again the following year, however, when he reported on the matter in the Transactions of the British Association for the Advancement of Science. 'During the exhibition of a panoramic model of Edinburgh, in the Zoological Gardens at Liverpool, on Sept 27, 1846, about 3pm, an erect image of Edinburgh, depicted on the clouds over Liverpool, was seen by two residents in the Great Park at Birkenhead, for a period of forty minutes,' he wrote.
