The Astrolabium Choir was established in October 1999 and has grown from a small group to an ensemble of approximately 40 choristers. While they all have professional or academic commitments, they find time to pursue their passion for singing together. Initially, the choir rehearsed at the Toruń branch of Caritas. From July 2001 to September 2003, the ensemble conducted artistic activities under the auspices of the academic church of the Jesuit fathers. From September 2003 to December 2011, they were affiliated with the Higher School of Banking in Toruń.

The name ASTROLABIUM symbolizes the choir’s connection to the city of Copernicus, as the Toruń-born astronomer is often depicted with this instrument in hand. For the choristers, the name represents their aspirations and the challenges they face in promoting their city at home and abroad, becoming a source of pride for Toruń. Their success in achieving this goal is evidenced by the Thorunium Medal, an honour bestowed upon them by the Mayor of the City of Toruń. Since its establishment, Astrolabium has actively participated in the cultural life of Toruń, engaging in various events, festivals, and competitions both domestically and internationally. The choir performs a diverse repertoire, including religious, secular, folk, and pop music, with a special focus on works by contemporary composers. In addition to a capella performances, the choir collaborates on numerous vocal and instrumental projects.
