Attention is drawn to the fact that despite 30 years of the participation of archaeology in studies on Polish historic towns, the archaeological method is still not always employed in preparatory works for the revalorization o f old and historic towns. Examples of not understanding the need to employ the archaeological method in urbanistic planning on the site of historic towns can be found in the 1st Regional Exhibition of Plans for Historic Towns Spatial Development, held in Rzeszów in 1977. The author points out that in 1979 the archaeologists uncovered in Piotrków Trybunalski town building grounds in 3 levels, dating back to 15th—17th centuries, in which one can distinguish an iterative contour of the town plot and o f the street. In 1978 the archaeologists uncovered and identified in Przedbórz-on-Pilica changes in the building arrangement and shifts in the regulating lines of the northern frontage o f the market in 17th— 19th centuries. The conclusions drawn from the Cracow symposium that took place in February 1979 should absolutely reach the consciousness of the people preparing the revalorization of historic towns.
