Entrance to the Menagerie
If there's no line, you might miss the entrance so look carefully.
Tip: It usually saves to take young kids in a stroller to Paris attractions--both for your arms and pocketbook as fees often are waived for kids in strollers.
The sign by the entrance can be loosely translated as:
"Open to the public in 1794, this Menagerie received the last animals of the royal menagerie at Versailles. It is the second-oldest zoo in the world. Napoleon the First directed the construction of some of the first buildings. The Menagerie is a historical monument, specializing in endangered species: 2,000 animals live peacefully here including small mammals, colorful birds, impressive reptiles and venomous invertebrates, permanently replacing large mammals like giraffes, elephants, hippos, bears, lions and tigers."
