The Ishango Bone was discovered there in 1960. This fossilised baboon bone, which was dated at 18,000 BC, has clear markings suggested to be either tally marks, a series of prime numbers, or a lunar calendar.
Ishango is home to the last significant population of hippos on Lake Edward, a lake which formerly held the biggest hippo population in the world.
Ishango is currently managed under the leadership of a park warden and five rangers. It has an airstrip, and administrative building, four houses and some tented accommodations for visitors. The buildings were rehabilitated by the European Development Fund in 2007.
