From the Discovery Channel: Romans in ancient Britan often lived in what were the equivalent of suburbs.
Consider the etymology of suburb:Jan. 20, 2005 — A spa treatment followed by a trip to the suburbs for a bit of shopping and dining sounds like a day in the life of a wealthy suburbanite, but it also could describe someone's schedule from around the 1st century A.D., as archaeologists in Bath, England have identified an ancient suburb located outside of Bath's main city center.
Since suburbs dating to the Roman period also have been found around other major cities, such as London, the finding adds to the evidence that suburban living is not a modern phenomenon.
The derivate suburb, suburbe before 1325, comes from the Latin word suburbium and dates back to the 14th century, but was only infrequently used before the 1800s. Suburban, another derivate, is borrowed from the Latin suburbanus (near a city). This word dates back to the 17th century. Before 1625 it had the meaning: of, relating to, or in a suburb.
