Park Collegium is reviving a fantastic musical heritage. With bits and pieces gleaned from various compositions in the Mechelen Choirbook, they’ve composed an all-new polyphonic mass – a piece never heard before. This madrigal music from the Flemish Renaissance comes straight from the antique pages of the Mechelen Choirbook. This melodic masterpiece is the master calligrapher Petrus Alamire’s sole manuscript, preserved in Leuven for over 500 years.

Park Collegium explores the polyphonic music of the 15th and 16th centuries as a living laboratory at the intersection of artistic practice and scientific study.

The internationally renowned Alamire Foundation is a pioneer in the study of music from the Low Countries. The Foundation unites musicians and scholars in the study of polyphony and the Gregorian tradition and brings this music to life through Park Collegium’s own house ensemble.

  • Daily at 6 p.m., 8 p.m., and 10 p.m. (30 min.)
  • Location: Park Abbey Church

The ambient soundscape that greets you in the beautifully restored Library of Voices at the Norbertuspoort (Norbertine Gate) soothes the soul. The voices of Cappella Pratensis resurrect the 16th-century Gregorian chant of Antifonarium Tsgrooten (Antiphonarium of Tongerlo). Antonius Tsgrooten was the abbot of Tongerlo who commissioned this musical masterpiece in 1522. And it wasn’t until the seventeenth century that his illuminated manuscript fell out of fashion. All in all, it’s a testimony to the eternal youth of Gregorian chants.

The Library of Voices is a contemporary rendezvous point, where books, digital images, and sound intersect, waiting to be discovered with cutting-edge technology.

  • Daily from 5 p.m. to 10:00 p.m. (15 min.), starts every half hour

Musa Horti has been associated with Park Abbey for over 25 years, where it rehearses every Sunday evening. 33 dedicated singers make up this vocal ensemble, directed by Peter Dejans since its establishment in November of 1989. Their mission is to actively seek out rarely performed, elite music from all eras – especially contemporary choral pieces – driven by a fervent and insatiable desire to tread new, unexplored ground.

American saxophonist Don-Paul Kahl will be joining the ensemble especially for the occasion. Set in the majestic Park Abbey Church by moonlight, it promises to be a once-in-a-lifetime dynamic artistic experience.
