Florentines like to think that the church was founded in 800 AD by the first Holy Roman Emperor. Charlemagne, but it more likely dates to 1059-1100. The church has a simple Romanesque facade and the basilican plan typical of early Christian churches, but with 16th-century side aisles. Santi Apostoli fronts Piazza del Limbo, so called because there was a cemetery here for infants who died before they were baptized. Hence, according to medieval theology, their souls dwelt in limbo halfway between heaven and hell.
