Belitung shipwreck
The Belitung shipwreck (also called the Tang shipwreck or Batu Hitam shipwreck) is the wreck of an Arabian dhow that sank around 830 AD. The ship completed its outward journey from Arabia to China but sank on the return voyage from China, approximately 1.6 kilometres (1 mi) off the coast of Belitung Island, Indonesia. The reason the ship was south of the typical trade route when it sank remains unknown.
