The tower, the priceless relic of native architecture, and the dignified walls of the past St. Michael's Collegiate Church are intrinsically linked in time with the later and the newest buildings of contemporary Marshal Stanisław Małachowski High School. To sense the magnificent atmosphere it suffices to go down the narrow shadowy stairs to the basement of the 13th century edifice housing the priceless School Museum.
The redecoration of the lower part of the collegiate building and its adaptation for the museum finished in 1980. On the 800th anniversary day St. Małachowski School Museum was opened, in the Romanesque & Gothic space. The exhibition is divided into historical and contemporary parts. It is changed periodically and the collection is continuously enlarged by the graduates and friends of the School.
