Join us to celebrate the Maryland Zoo’s 150th birthday with a new walking tour around its historic grounds led by Zoo staff. Discover the history of the zoo and several of its important landmarks, including iron-barred cages and other structures built when the Rogers Mansion was still a private residence. As we walk, we’ll hear about the zoo’s first elephant, Mary Ann, and we might even glimpse some penguins. We hope you’ll join us to experience a walk through the past, which will showcase how far zoological organizations have come from menageries of exotic creatures to expert conservation centers for endangered species!
