Great Zimbabwe and Its Walls of Stone
In southern Africa, in the country now called Zimbabwe, stand the ruins of a once-great city. Today it is known as Great Zimbabwe. Many centuries ago, thousands of people lived there, and it was an important center of trade and power.
The most striking thing about the city is its stone walls. Builders cut granite into blocks and stacked them in tidy rows, and they used no mortar to hold the blocks together. One curving wall in the area called the Great Enclosure is taller than a house, and it circles a wide space. People still wonder exactly how each wall was used, but they surely showed the strength of the rulers who ordered them built.
Great Zimbabwe grew rich through trade. People there raised cattle, and merchants carried gold and ivory from the region toward cities on the coast of the Indian Ocean. From the coast, goods traveled by ship to lands far away. Archaeologists have found glass beads and pottery that came from distant places buried in the ruins, which is evidence of this long-distance trade.
Scholars have also shown that the ancestors of today's Shona-speaking people built the city. In time, people moved away from Great Zimbabwe, perhaps because food or firewood ran short, but nobody knows for sure.
