Sigismund Bell


Latern. Both sound and light are waves: mechanical and electromagnetic. Is it possible to build a bridge between the two, to convert an acoustic wave into an image and thus see sound? In physics, this phenomenon is known as sonoluminescence and is the subject of intense scientific research. The concept of combining the sound of a bell with laser light will appear in the multimedia performance. On 13 July 1521 Krakow heard the Sigismund Bell ring for the first time. 500 years later, a beam of laser light was triggered by the sound of the bell, thereby becoming a kind of a lighthouse/latern in the city space.

Study for One Bell Stroke, conceived by Prof. Marek Chołoniewski, is an international electroacoustic music competition dedicated to Włodzimierz Kotoński, author of the first Polish electroacoustic composition “Study for One Cymbal Stroke” performed in the Polish Radio Experimental Studio in Warsaw in 1959. The competition was coordinated by the Polish Society of Electroacoustic Music. The Winners Concert took place at the foot of the Wawel Castle / Sigismund Tower on 13 July at 21:00. (,

500×1 and is a concept developed by Prof. Grzegorz Biliński in form of an Open Call and realised by students of the Academy of Fine Arts in Kraków.  Dozens of 1-minute audiovisual compositions/video clips were received from all over the world and used to create a multimedia spectacle presented at the Wawel Castle on July 13, 2021. They were presented in selected areas of the city of Kraków on 10-13 July 2021 (MOS and galleries of Fine Arts Academy). (

AR mobile.
Zygmunt AR by Karina Gorzkowska and Maja Szerel is the augmented reality application that shows visualizations of the spread of sound when you scan the Sigismund Tower by mobile phone. The forms emerging from the tower show an abstract record of the events and times he witnessed. His heart has broken three times, but he still beats and is one of the most important symbols of Krakow.
