Aquarium de Paris
The Paris Aquarium is not only Europe's oldest aquarium (it was built in 1867), for years it was also Europe's largest. Housed in the center of the city, on the quarries where Napoleon would house his cavalry, this institution has been part of the fabric of Parisian life for more than a century.
This institution embodies the late 19th century fascination with the spectacular. Alongside bearded ladies and camera obscuras, aqua vivariums were all the rage. With 4 million liters of water, and 10,000 fish from around the world, there's plenty to keep you and your family entertained here for hours on end.
