Ngome Kongwe
Coral-stone fortress raised over a Portuguese church, itself built atop a medieval mosque and a tenth-century well.
This guide to Ngome Kongwe, the Old Fort, in Zanzibar City starts with a 2017 to 2022 excavation that cut through the courtyard floor and found four buildings stacked one on the last, reaching back roughly seven hundred years before the fort's own walls. It works through that sequence layer by layer: a sand-scooped well ringed by daub huts, a small thirteenth-century coral mosque, a Swahili stone house, and an Augustinian church the Portuguese built in the early 1600s, complete with burials researchers still hope to identify. Stand in the courtyard and picture the layers beneath your boots, each building squared over the one before it.
