Paris is home to what many consider the oldest "modern" zoo in the world, the Jardin des Plantes. It is also home to the Vincennes Zoo. Like many older zoological parks, Vincennes was showing its age, and six years ago the decision was made to close it for major repairs (I personally would love the chance to shutter my zoo for a few years, tear it down, and rebuild it... and I'm sure I'm not alone in that). The zoo is now reopened and, by all accounts, is a hit with the public. Best of luck to the staff and animals.
