What is "valdezia"

Valdezia is a sprawling rural settlement situated at the foothills of the Soutpansberg mountain range in Limpopo Province. It is roughly 10 km east of Elim Hospital in the Hlanganani district in the former Gazankulu homeland, South Africa. Formerly known as Klipfontein, it was the site of a Swiss mission station, and it was named after the Swiss canton of Vaud. Valdezia's population, according to the official census of 2011, currently stands at between 7,600 and 8,000 people. It is considered the birthplace of the written Tsonga language in South Africa.
