How a zoo’s sights, sounds and smells can benefit people with dementia
Tour programmes at Berlin Zoo for people with dementia are helping them feel part of society and even jogging happy childhood memories

Christel Krueger stared in awe at a mother hippopotamus and its offspring sleeping on a sandbar through the thick glass and murky water of their enclosure at the Berlin Zoo.
Krueger, 86, and her daughter were on a specialised zoo tour in March for people with dementia that was organised by Malteser Berlin, part of the international Catholic aid organisation The Sovereign Order of Malta.
On the tour with Krueger, Ingrid Barkow watched from her wheelchair as the elephants roamed their habitat, while Monika Jansen balanced on her tiptoes to get a better view of a rhinoceros.
“When I get home, I’ll still be thinking about it,” said Jansen, 85. “Maybe even at night, while I’m sleeping and dreaming about it.”
