THE CHAGGA CAVES In the days of colonization and when the Maasai moved into Tanzania, the Chagga people lived in fear. They build an elaborate system of caves and tunnels to protect themselves and their livestock. These tunnels at least five metres underground with narrow areas designed to attack any enemy who may have found the caves. A kitchen area was designed with special vents to draw smoke out of the living area and into a hidden location where it would not be seen. The kitchen fire provided the only light in the caves. The construction of these caves is an architectural wonder. These caves are also inhabited now by bats, that added to the eeriness of the surroundings.
