The Great Zimbabwe, is a complex of stone ruins spread out over a large area in modern-day Zimbabwe, which itself is named after the ruins. It is a medieval city in the south-eastern hills of Zimbabwe near Lake Mutirikwe and the town of Masvingo. It was the capital of the Kingdom of Zimbabwe during the country’s Late Iron Age.The word “Great” distinguishes the site from the many hundred small ruins, known as Zimbabwes, spread across the country. Built by indigenous Bantu people, the construction started in the 11th century and continued for over 300 years. At its peak, estimates are that Great Zimbabwe had as many as 18,000 inhabitants. Causes for the decline and ultimate abandonment of the site have been suggested as due to a decline in trade, political instability and famine and water shortages caused by climatic change.
