Franceville
The main city of the southeast, terminus of the Trans-Gabon railway and a research centre.
Updated 16 October 2026
Franceville sits on the upper Ogooué in the southeast, founded as a settlement for freed slaves in 1880 and now the region's main city and the terminus of the Trans-Gabon railway. A large biomedical research institute operates there, and the uranium mines at nearby Mounana produced one of the strangest scientific findings of the twentieth century when the ore at Oklo turned out to have sustained natural nuclear fission around two billion years ago.
Background
Pierre Savorgnan de Brazza founded the town on 13 June 1880 on the site of a village called Masuku. It was meant as a home for Africans freed from slavery on the coast by Brazza and his party, and he named it Francheville, a free town. People have lived in the upper Ogooué valley for at least two millennia. The brick Saint-Hilaire church, put up in 1899, is among the oldest buildings still standing in the upper Ogooué. The 2013 census counted 110,568 residents, making it Gabon's third-largest commune. The Université des Sciences et Techniques de Masuku is based here, as is the CIRMF, a biomedical institute known for its work on Ebola.
