Punnathoorkotta is the largest single place for captive elephants in the world. It houses more than 60 elephants of Guruvayoor temple. Once this had been the palace of Punnathoor Raja, the Zamorin king. Just three kilometres from Guruvayoor Sree Krishna Swamy temple, Thrissur, Kerala, this fort attracts many travellers and devotees. Within the fort there are water tanks for the elephants to have a bath. During the Malayalam month of Karkidaka, the tuskers are given "sukha chikitsa"(restorative treatment).
