The Corpus Christi church is one of the oldest and most interesting monuments of sacred art in Krakow and so it is visited by numerous groups of tourists. The recording was made while about 20 people were visiting the temple. Although everyone tries to keep quiet, every rustling sound is amplified by the architecture of the building. Silence turns out to be impossible.
