1. Aquarium of Genoa
Italy's largest aquarium opened in 1992 as part of the Porto Antico regeneration project, designed by Renzo Piano to mark the 500th anniversary of Columbus's first voyage. The timing was deliberate — Genoa, Columbus's birthplace, used the Expo 1992 to announce its revival as a modern city. The aquarium now draws over 1.2 million visitors a year and is run by Costa Edutainment.
Inside, more than 12,000 animals from over 600 species are spread across 70-plus tanks. The Shark Bay is the obvious crowd-pleaser, but the Cetacean Pavilion — with dolphins and beluga whales — and the Ice Kingdom with its penguins are equally worth the time. Tanks recreate habitats from tropical reefs to Arctic waters, so the scale of the collection genuinely surprises first-time visitors.
For families, this is probably the single best things to do in Genoa on a full day. Buy tickets online beforehand — weekend queues stretch well back along the waterfront, and prices are cheaper when booked in advance. Allocate at least three hours if you want to move at a reasonable pace.
