The Cave School, also known as Tenzug School, is a historic school site sheltered under a rock overhang in the Tongo Hills near Tenzug and Tongo in the Talensi District of Ghana's Upper East Region. Formal education here began at some point between 1965 and 1985, with an initial pupil population of 25. Separate areas of the rock were mapped out for classrooms and for cooking and eating, so the overhang itself served as the school's physical layout.
The site is no longer the community's working school. A proper school has since been constructed by the government beside the original Cave School, following the community's own construction of a three-unit classroom block that was later absorbed into the public system. What remains is a heritage site rather than an active classroom, and it is listed among the features visitors see in the Tongo Hills, alongside the Chief's Palace and the donkey, hyena and hiding caves.
The wider setting gives the site its context. The Tongo Hills are the sacred epicentre of the Talensi people, with archaeological evidence of human use of the caves and shrines dating back to 500 BC, and the area was proposed for UNESCO World Heritage listing under the Tenzug–Tallensi settlements tentative list. Tongo itself is a small town near Bolgatanga, the Upper East Regional capital, and is the capital of the Talensi District; the community of Tenzug sits at the end of a U-shaped valley in the hills. The Tongo Whistling Rocks are about 10 km from Bolgatanga.
Visiting the tourist sites in the Tengzug area attracts a fee, as reported: GH¢20 for Ghanaian adults, GH¢10 for students and GH¢150 for researchers; for non-Ghanaians, GH¢30 for adults, GH¢25 for students and volunteers, and GH¢10 for children under 12. Entering the shrine may attract additional donations to the elders, with no fixed amount. Fees and arrangements can change, so confirm current details locally before travelling.
