Building a Zoo requires a Colosseum or any of its replacements.
The oldest known zoological menagerie (or "zoo") has been excavated at Hierakonpolis and dates to c. 3500 BC; the oldest existing zoo, the Tiergarten Schoenbrunn in Vienna, evolved from the exotic animal collection maintained by the Habsburg dynasty and was opened to the public in 1765 AD.
