Suburra was part of ancient Rome, located in a valley between the southern end of Viminal and the western slopes of Esquiline. In ancient times, at first it was a separate settlement, then incorporated into Rome, finally became a crowded district inhabited by the urban poor (very often in insulae). Suburra was also known as the Red Light District.
Julius Caesar’s family home was in this part of the city. The dictator spent part of his childhood there.
