How many stars might be in the sky? Millions? Billions? Well, the little Mausoleum of Galla Placidia in Ravenna counts 570 golden stars, all in mosaic and shining on an intense blue sky with at its centre a big latin cross, the symbol of resurrection.
It was built in the first half of the 5th century A.D. by empress Galla Placidia and it is a unicum in the entire world. In small groups you enter inside and, silently, you admire what heights human mind can reach when it meets infinity.
