One of the most remarkable features of the site is its walls. As Manyanga explained, "The style and scale of dry-stone walling that constitute Great Zimbabwe is unparalleled elsewhere in Africa and beyond." The walls of the Great Enclosure are 6m wide and 11m tall, and they run about 250m, making the enclosure the largest single structure in sub-Saharan Africa and the second largest on the continent by total area: only the pyramids in Egypt exceed them in size according to Manyanga.
