Though visitors usually go straight to see the giant pandas, don't miss the other interesting animals, like tigers from the northeast, yaks from Tibet, enormous sea turtles from China's seas, and red pandas from Sichuan. The zoo started out as a garden belonging to one of the sons of Shunzhi, the first emperor of the Qing dynasty. In 1747, the Qianlong emperor had it refurbished (along with other imperial properties, including the summer palaces) and turned it into a park in honor of his mother's 60th birthday. In 1901, the Empress Dowager gave it another extensive facelift and used it to house a collection of animals given to her as a gift by a Chinese minister who had bought them during a trip to Germany. By the 1930s, most of the animals had died and were stuffed and put on display in a museum on the grounds.
