The country itself is named after these walls: dzimba dza mabwe, "houses of stone". Built between the 11th and 15th centuries by ancestors of the Shona, Great Zimbabwe was the capital of a powerful trading kingdom and is the largest ancient stone complex in sub-Saharan Africa – a UNESCO World Heritage Site since 1986 and the most important historical site among Zimbabwe tourist attractions.
During the colonial era, many Europeans refused to believe that Africans had built the city, attributing it instead to Phoenicians or the Queen of Sheba. In 1929 the archaeologist Gertrude Caton-Thompson showed conclusively that it was of African origin, a finding confirmed by every study since. The city declined in the 15th century, probably as resources were exhausted and trade shifted north, and power passed to successor states such as Mutapa and Torwa, whose capital was at Khami near Bulawayo.
Up to 18,000 people lived here at its height, trading gold and ivory with the Swahili coast, Arabia, India and China. Its mortarless walls remain an astonishing feat of medieval African engineering.
Archaeologists have found Chinese celadon, Persian pottery and glass beads from the Indian Ocean trade, proof of the city's far-reaching connections. The walls of the Great Enclosure contain around a million granite blocks, shaped and fitted together without mortar in elegant curves and chevron patterns. Walking through its narrow passages and among the granite boulders of the Hill Complex gives a powerful sense of a sophisticated African civilisation.
The site is about 30 kilometres south-east of Masvingo, four hours from Harare. Footpaths link the three main areas, and guides at the entrance bring the ruins to life. As public transport is limited, most visitors arrive on a guided itinerary such as the 10-day heritage and wildlife tour.
The three areas are the Hill Complex, the Great Enclosure and the Valley Ruins between them. Two paths lead up to the Hill Complex: the steeper Ancient Ascent, following the original route through narrow rock clefts, and the gentler Modern Ascent.
The climb to the Hill Complex is steep; allow at least half a day for the whole site.
Wear good walking shoes and bring water and sun protection, as there is little shade. Hiring an official guide at the entrance is highly recommended, both for the history and to help you find your way through the complex.
Dry months from April to October are best for walking; sunrise gives the warmest light on the stone.
The rainy season from November to March brings green surroundings and dramatic skies but can make paths slippery. Midday in October can be very hot.
Lodges overlook nearby Lake Mutirikwi, and a campsite sits by the entrance.
The lake's recreational park is home to white rhinos, giraffes and antelope, and makes a pleasant addition to a visit to the ruins. Masvingo town has supermarkets and simple restaurants.
Victoria Falls is the natural wonder; Great Zimbabwe is the cultural treasure. Pair it with Matobo National Park, or see both on the 14-day Zimbabwe expedition tour.
The Khami Ruins near Bulawayo, also UNESCO-listed, continue the story of the region's stone-building civilisations and can be visited on the way to Matobo.
Stay nearby to walk the ruins at dawn, when the stone glows and the crowds are absent.
