what feature is found in the hill complex of the great zimbabwe
Great Zimbabwe The ruins form three distinct architectural groups. They are known as the Hill Complex, the Valley Complex and the Great Enclosure. The Hill Complex is the oldest, and was occupied from the ninth to thirteenth centuries. The Great Enclosure was occupied from the thirteenth to fifteenth centuries, and the Valley Complex from the fourteenth to sixteenth centuries.[6] Notable features of the Hill Complex include the Eastern Enclosure, in which it is thought the Zimbabwe Birds stood, a high balcony enclosure overlooking the Eastern Enclosure, and a huge boulder in a shape similar to that of the Zimbabwe Bird.[16] The Great Enclosure is composed of an inner wall, encircling a series of structures and a younger outer wall. The Conical Tower, 5.5 m (18 ft) in diameter and 9 m (30 ft) high, was constructed between the two walls.[17] The Valley Complex is divided into the Upper and Lower Valley Ruins, with different periods of occupation.[6]
