In 2012, the Tomb of Askia was added to the African endangered heritage list as reported by African World Heritage Sites. The Tomb of Askia which is located close to the banks of the River Niger was built in 1495 in Gao, Mali. The structure stands about 17 meter high and was made from hardened mud.
From the early 15th century to the late 16th century, the Songhai (or Songhay) empire not only controlled vast part of West Africa but it had also become a major trading center for gold and salt. Gao which was initially the capital of Gao empire then became the capital of Songhai empire. The Tomb of Askia symbolizes a major period in the history of west Africa and its gradual destruction is a significant loss.
