ILVB 

The Illustre Lieve Vrouwe Broederschap (ILVB) is a brotherhood dating back to 1318, located in the Brabant city of 's-Hertogenbosch. Today, this ecumenicalcommunity  is comprised of  eighteen Catholic and eighteen Protestant members, each holding a prominent societal position. The brotherhood "cares for its centuries-old material and immaterial cultural heritage, promotes Christian unity and brotherly bonds, while always being mindful of developments and challenges in modern times." The word 'illustre' translates literally as “illustrious” and refers to the Virgin Mary. The society is currently based in the Zwanenbroedershuis in 's-Hertogenbosch, of which Cappella Pratensis is the proud co-occupant.
The Zwanenbroedershuis also serves as a museum. Its rich collection includes eleven religious choir books of the Brotherhood, most of which date from the 16th century. Nine of these books contain a wealth of polyphonic music, as well as several which  feature  collections of Plainchant.

Alamire Foundation

The Alamire Foundation was established in 1991 as a collaborative initiative between KU Leuven, the Research Unit of Musicology, and Musica, the Impulse Center for Music. As an international study center, the Alamire Foundation aims to stimulate, coordinate, and conduct scientific and practical research. It focuses specifically on music and musical life in the Low Countries from the Middle Ages to 1800, with particular attention to mapping and making available unknown or unexplored material. Using state-of-the-art methods, including digitalization, this musical heritage is conserved, studied, and valorized. The music, whether in manuscript or print, is made accessible both through traditional publications such as  inventories, facsimiles, and critical text editions, and through innovative digital databases. Scientific discussions and conclusions are disseminated in monographs and professional journals, including the foundation’s own Journal of the Alamire Foundation. Collaborations and contacts with the academic and performance worlds, heritage institutions, and the cultural sector result in international conferences, music labs, festivals, concerts, exhibitions, and multimedia applications. 

The Alamire Foundation is located in the impressive complex of Park Abbey in Leuven/Heverlee. Cappella Pratensis serves as the foundation's ensemble in residence.
