Tanzania
A stone-channelled city fed forty thousand people, then everyone walked away.
Somebody built a city of stone channels here, irrigated fields for tens of thousands, farmed it for three centuries, and then walked away. Nobody knows quite why. The channels still lace the escarpment's foot.
Engaruka is the Rift's quiet enigma: the stone-built remains of an irrigation settlement covering some twenty square kilometres, occupied from roughly the fifteenth to eighteenth centuries and supporting a population estimated toward forty thousand before its unexplained abandonment. The terraces, channels and field walls read clearly on a guided walk from the modern village, where a women's group cooks a meal on request and fresh produce is the local table. Start early; the Rift floor heats fast.
