Planetario Galileo Galilei

A 1966 flying-saucer dome in Palermo's lakes district — a retrofuturist concrete shell that looks like it touched down from a more optimistic future, surrounded by parkland and ponds. Inside, the saucer hides an immersive star theater that has introduced generations of porteños to the night sky. By day the building itself is the attraction: a beloved piece of mid-century space-age optimism, especially photogenic against the surrounding greenery. For visitors, it's both a charming architectural oddity and a working planetarium, set in one of the city's loveliest green spaces.
