Originally meaning a single-room shop for the sale of goods and services, tabernae were often incorporated into domestic dwellings on the ground level flanking the fauces, the main entrance to a home, but with one side open to the street.
According to the Cambridge Ancient History, a taberna was a "retail unit" within the Roman Empire and was where many economic activities and many service industries were provided, including the sale of cooked food, wine, and bread.
The plural form tabernae was also used to denote a way-station or hotel on roads between towns where genteel travellers needed to stay in something better than cauponae, and when the official mansio was not open to them.
Livy writes about an encounter that Marcus Furius Camillus, a Roman general present during the expansion of the Roman Republic in the 5th and 4th centuries BC, had with tabernae of Tusculum, a city in the Latium region of Italy: Camillus having pitched his camp before the gates, wishing to know whether the same appearance of peace as was displayed in the country prevailed also within the walls, entered the city, where he beheld the gates lying open, and everything exposed to sale in the open shops, and the workmen engaged each on their respective employments...
A good site will have helped to maximize a retailer’s net selling potential and for this reason, tabernae will normally be located within reach of their markets.
Although the occupation of a merchant was not highly regarded in Roman culture, it still pervaded the freedman class as means to establish financial stability and eventually some influence within local governments.
