The Hill Complex of the Great Zimbabwe ruins are some of the oldest and largest structures located in Southern Africa. Construction of the stone buildings started in the 11th century and continued for over 300 years.
The Hill Complex is the oldest part of Great Zimbabwe, and shows signs of construction that date to around 900 AD. The walls were constructed using dry-stone masonry techniques, which involved carefully stacking and shaping the granite blocks without the use of mortar. Also, about 70 percent of the walls are original. (Oct. 28, 2024)
