Bananaversary marks the anniversary of the rescue of the 266 chimpanzees from the Coulston Foundation. On September 16, 2002, Save the Chimps’ late founder Dr. Carole Noon was handed the keys to one of the most notorious primate research labs in history, The Coulston Foundation. In that instant, 266 chimpanzees locked away in their barren cages were rescued from years of exploitation as medical research subjects and given the promise of a new and brighter future. This remains the largest single rescue of chimpanzees in history.

This historic day has become known at Save the Chimps as “Bananaversary” and is celebrated each year with banana-themed enrichment parties for the chimps.
