The BBC has a an article and a short slideshow of the new Gorilla enclosure at London Zoo. Their new home cost about £5.3m to construct.

Gorilla Kingdom consists of a large open island, surrounded by a moat, an indoor "gym" and a back den.

Three western lowland gorillas will live in the enclosure: Bobby, a 23-year-old male; and two females, Zaire, 32, and Effie who is 13.

The £5.3m project means that Bobby can see the sky without bars for the first time since he was captured as a baby.
