The Church of São Francisco de Assis is the most photographed building in Belo Horizonte and one of the foundational works of Brazilian modernism. Niemeyer designed it in 1943 as a series of low parabolic concrete vaults, abandoning the right angles and pointed arches of traditional church architecture entirely. On the rear exterior wall, the painter Cândido Portinari executed a long azulejo tile mural — a hallucinatory blue-and-white representation of the life of Saint Francis.
Inside, the church is small and quiet. Portinari's painting of Saint Francis appears again behind the altar — a darker-skinned Francis than Catholic iconography traditionally allows, which is part of what scandalised the church at the time. Open during daylight; the lakefront walk continues around the building.
