Tata Somba region
The Somba people (also known as the Tammari people) are an Oti-Volta-speaking people in the far north of Benin and Togo. They are famous for their two-storey fortified houses, known as Tata Somba ("Somba house"). The ground floor is used for housing livestock at night, internal alcoves are used for cooking, and the upper floor contains a rooftop courtyard and is used for drying and storing grain as well as sleeping quarters. These evolved by adding an enclosing roof to the clusters of huts joined by a connecting wall that are typical of Gur-speaking areas of West Africa.
