Suburra (usually spelled Subura in antiquity) was an area of the city of Rome, Italy located below the Murus Terreus on the Carinae. 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. Most of its inhabitants lived in insulae, tall apartment buildings with tabernae on the ground floor.
