The Primate Rescue Center in Nicholasville is only open for tours one day a year.
Saturday, the people that support the sanctuary financially were able to walk through the home of more than 50 chimpanzees and monkeys.
The center, whose mission is to alleviate the suffering of primate, is completely funded by private donations.
Workers say without the community's donations, they wouldn't be able to offer such a high quality of care to the animals.
