In 1470 the canon Helias Helye (1400-1475) printed the book “Mammotrectus super Bibliam” by the Italian Franciscan monk Johannes Marchesinus in his printing house in Beromünster. The book has six hundred pages and is a textbook for the understanding of the Bible. The book also contains a date, making it the first printed book with date of production in Switzerland. On the occasion of this anniversary, the three Beromünster cultural institutions, the Schlossmuseum, the Haus zum Dolder and the Beromünster Abbey are organising various events in the field of printing, books, paper and writing. As the former location of the printing house, the Schlossmuseum focuses on the production of books and the functioning of the (reconstructed) printing house.
