Great Zimbabwe, located near the modern town of Masvingo, became the most impressive symbol of political and economic development between the Zambezi and Limpopo. Early Iron Age occupation existed on the Acropolis Hill before the fourth century of the Christian era, but the site was not yet significant. Later Iron Age settlement began about the tenth or eleventh century, when Gumanye communities occupied the area before the construction of the great stone walls.

By the twelfth century, the culture of the settlement had changed substantially. Pottery became more finely finished, clay human figurines were produced, imported beads increased, and more substantial mud-and-pole buildings appeared. Copper, bronze, and gold ornaments multiplied, while stone walling came into extensive use; from the thirteenth century, stone structures replaced earlier huts and the western enclosure developed into a major architectural complex.

The Great Enclosure was built progressively during the following century. Its free-standing wall averaged 7.3 metres in height, measured 5.5 metres thick at the base, and contained a rubble core faced with horizontal masonry. A decorated section, inner enclosures, substantial house foundations, and a conical tower formed an imposing complex that was presumably associated with the rulers. The Acropolis, valley settlements, and enclosure together reveal a large and socially differentiated centre.

The archaeological deposits contain gold and copper ornaments, soapstone bowls and carvings, glass beads, and Chinese, Persian, and Syrian ceramics dating from the fourteenth century. These finds show that East African coastal trade penetrated far into the interior and that Great Zimbabwe was an important commercial centre. The site's architecture is presented as an essentially African development, using local granite blocks and extending building practices found in other African chiefly enclosures.
