This natural architecture served a crucial purpose, defining the cave not just as a shelter, but as an impenetrable fortress. Indeed, the history of human interaction with Nyakagyera stretches back centuries, long predating modern documentation. The stone cave (giving its name to the local village of Omwibare, meaning stone,) was allegedly inhabited by early man, from where stones were thrown to kill animals lower down the slopes, and the dead animals would be taken inside for feasting. Later, the cave was also used as a place of safety where clan leaders could rest safely and plot against incomers, such as those from present-day Rwanda who attempted to spread into the area. The Batwa (pygmies) eventually took control of the cave; however, they were later forced from the recluse by the ancient Bakiga ("people of the mountains") who now populate the area. The Batwa were forced into the forests, where today they are better known as the pygmy people.
