The Zoological Garden, Alipore (also informally called the Alipore Zoo or Calcutta Zoo) is India's oldest formally stated zoological park (as opposed to royal and British menageries) and a big tourist attraction in Kolkata, West Bengal. It has been open as a zoo since 1876, and covers 18.811 ha (46.48 acres). It is probably best known as the home of the now expired Aldabra giant tortoise Adwaita, who was reputed to have been over 250 years old when he died in 2006.
