The paper focuses on the interrelations between the environment, urban space, and oxen trade. On the basis of sources from the region of Greater Poland, it discusses particular conditions of trade in livestock (routes, pace of driving the animals, the need to feed and give water to the oxen). It also points to thus far ignored issues connected with indispensable adaptation of the urban space to the needs of the large-scale oxen trade which flourished during fairs taking place in various towns and emphasises the necessity to carry out further research in this regard.
