A retirement home for elephants has opened in Burma's Shan State.

Green Hill Valley in Kalaw Township takes care of five animals who range in age from 41 to 52.

Tin Maw, one of the managing directors said: "Each of them, you know, have their own little problems. For example, one has a problem with its eyes and another elephant also has a problem with its eyes, and one has a problem with its heart.

"Some of them were attacked by wild elephants in the forest so they got infections."

Maw and her husband opened Green Hill Valley in 2011 as part of their commitment to "responsible tourism", they say they want tourists to see elephants not as creatures for entertainment, but as animals living in their natural habitat.

The camp is also home to nine mahouts, elephant trainers who develop a close bond with the animals and sleep in huts in the mountains to stay near them.
