Nature and extent of economical activities in "small towns" of Belgian Gaul and Germania Artisanal and commercial activity in the secondary agglomerations represent an economic phenomenon that is most often studied on the basis of data on the nature and distribution of products and those on the corresponding work structures. The communication proposed, starting from the well-documented example of artisan neighbourhoods of the vicus of Bliesbruck put into perspective with comparable researches in other vici (Schwarzenacker, Mâlain, Vitudurum), to address this issue through the study of the homes that house these activities (area of houses, architecture and home equipment, respective roles of housing and work space) and the lifestyle of those who are at the origin (development of houses and archaeological artefacts discovered).
