The island of Sumba in eastern Indonesia is home to the Pasola festival - a potentially fatal spear-throwing fight on horseback.
Sometimes called the Forgotten Island, Sumba's people still follow ancient customs and traditions. Their unique thatched houses have three levels: the lower one is for livestock, the middle is for humans (women in rooms on the left, men on the right) and the top level is where is the ancestors live.

The Pasola is held every year in February or March when the Nyale, or sea worms, can be found in the shallow waters. The coming of the worms marks the end of the wet season and the time to begin planting rice – and the time to saddle up and throw spears at your rivals.
The ancient fighting game involves two teams of men on horseback charging towards each other with spears. It's a dangerous sport; players and even spectators can be injured or killed. It is believed that any spilled blood will fertilise the land and increase the year's rice crop.
