Basilique Sainte-Anne

Cathedral in Brazzaville

This modernist 1949 building was the crowning achievement of French architect Roger Erell, who was known for fusing Western architectural ideas with local building techniques. It's easily one of the city's most striking buildings, with its dazzling green roof and carved copper doors – try to come by around 5pm for mass, when the nave is a sea of beautifully dressed locals.
