The topic of the research focused on small towns in peripheral areas (that is, outside metropolitan areas) in 3 voivodships in northern Poland (Pomeranian, Varmian- -Masurian and West Pomeranian). The author argues that the industry development in small towns can be an important development factor of peripheral areas. The author identifies the development level of the town industrial function and analyses their correlations with some of the features of the towns and their surroundings. He characterizes also most important industry in towns where the level of industry development is the highest. He is also searching for an answer to the question about factors of industry development in researched towns. In many cases in which spatial factors are difficult to explain by their configuration, coincidence can be said to play an important role.
