Ziwa, or Ziwa ruins (formerly Van Niekerk ruins after Major Pompey Van Niekerk who was second in command of the Afrikaner Corps) is the name used to describe the remains of a vast late Iron Age agricultural settlement that has been dated to the 17th century. The site is located in Nyanga, Zimbabwe. Ziwa was declared a National Monument in 1946 and is currently under consideration for World Heritage listing. The site contains a large variety of stonework structures including stone terraces running along contours of hills and steep landscapes. Archaeological investigations have also engendered important aspects of pottery and rock art.
