• Great Enclosure: Largest ancient sub-Saharan structure—1M+ granite blocks, 18 acres, 11m high walls—built without mortar.
• Hill Complex: Royal precinct on granite kopje; ritual platforms, monoliths, bird sculptures.
• Valley Ruins: Elite residences, cattle kraals, terraced platforms.
• Technique: Precision shaping, gravity locking, thermal expansion management—no mortar, no metal tools.

• Irrigation network: Dams, canals, terraced fields capturing seasonal runoff
• Water storage: Reservoirs sustaining dry-season agriculture
• Soil management: Mulching, crop rotation in savanna environment

3. Regional & Indian Ocean Trade

• Exports: Gold (from inland mines), ivory, copper, cattle, iron goods
• Imports: Chinese celadon, Persian glass, Indian beads, Arabian textiles
• Network: Linked to Kilwa, Sofala, Swahili Coast → India, China, Persia
