Suburra (usually spelled Subura in antiquity) was an area of the city of Rome, Italy located below the Murus Terreus on the Carinae.[1] In ancient Roman times, it was a crowded lower-class area that was also notorious as a red-light district. It lies in the dip between the southern end of the Viminal and the western end of the Esquiline hills.[2] Most of its inhabitants lived in insulae, tall apartment buildings with tabernae on the ground floor.
