The Écomusée Tata Somba, opened in March 2021 in Tanguiéta (Atacora department, 25 km from Pendjari National Park), is West Africa's first ecological museum. Dedicated to the architecture of the Tata Somba — the earthen fortress-dwellings of the Batammariba people, recognized as UNESCO World Heritage as part of the Koutammakou cultural landscape — it brings together the region's five traditional architectural models on a single site, safeguarding their building techniques and craftsmanship. The project links heritage conservation with ecotourism: it promotes income-generating activities for local women, the protection of endangered medicinal plants, and reforestation programs. Founded by Ibrahim Tchan and Yves Biaou with World Bank support.
