Roger Erell (of his true name Roger Lelièvre), born with Mansle (Charente) in 1907 and deceased with Vallauris (VAr) in 1986 is largest and most innovative of this generation of creative architects who equipped Brazzaville (capital of Congo) with an exceptional monumental ornament of 1940 at the Sixties. The essential idea of Erell: to combine the Western techniques with materials and the artistic inspiration buildings. It was one of the first to use the mauve sandstone which abounds with the accesses of the Congo river in its crossing of the Plate of the Cataracts. Its apogee is the Basilique Holy-Anne of Congo.
