The aquarium is one of the largest in Italy. Dozens of large aquariums and ponds where different species of fish are displayed from different corners of the world. There are rare fish brought from seas far away, like the Red Sea. A transparent tunnel allows visitors to see all the fish and sea creatures on all sides and it simulates walking deep in the sea.
A special experience to see in the aquarium in Milan is how they feed the various animals and to receive guidance and explanations about the lives of the various water creatures.
The Milan Aquarium opened in 1906, in honor of the World Fair that took place in the city. This makes it the third oldest aquarium in Europe and one of the oldest in the world.
