The abbey is of particular significance as the home of an especially skilled scriptorium and goldsmith's workshop, producing illuminated books and manuscripts, liturgical and ornamental pieces in gold for church use, and jewellery. This was set up by Roger of Helmarshausen, a highly skilled goldsmith and artist-monk, who moved to Helmarshausen from Stavelot Abbey in 1107. He is sometimes considered to be the author of the medieval treatise on art and crafts, De Diversis Artibus.
