In the introduction, the author recalls the history of the town, which for the first time was mentioned in 1145 as Villa and in 1239 as a castle-town. The establishment of a new town according to the Magdeburg law as well as the church of St. Alexis (today: St. Nicholas) and the royal court is ascribes to King Kaziimierz the Great (1333-1370). The town was located along an important communcation route from Little Poland via ts usage is evidenced by Poznaä in Great Poland. The frequency of its usage is evidenced by the number of days of sojourns in localities situated along the route (see: table). In the course of successive centuries, the town was expanded but also damaged by fires, floods and (especially the Swedish invasion of 1655-1656). At the end of the eghteenth ceuntry, attempts were made at an itroduction of a textile industry, but to no avail. On the other hand, the fact that the town was siituated along a pilgrimage route, leadin from Warsaw to Jasna G˘ra, was of great importance. In 1939, the Nazis destroyed three rows of houses in the market square, leaving the south-eastern row. After the war, the market square was filled with concrete, style-less buildings, totally negating the historical space. In 1978, critiical assessments of this project led to an archeological expert opinion intent on dating and estabilishing the range of development upon the basis of extant foundations or their negatives. It was found that the development originated primarily in the seventheen nad eighteenth ceuntries. Surface investigations of the architecture and the non-destroyed south-eastern row of houses disclosed vaulted arches of niches above all wiindow and door openings (walled up after the war) - traces of uniform architectonic order of the maket square development. The research suggested a delineation of building lots for residential housing, a proposal which was ultimately rejected.
