The symbol of a guild of cathedral vergers is the crossed keys. Black is the most common colour for priests, readers, vergers, and server cassocks. The society's members are actively cooperating with many church vergers in Norway. The cathedral usually has one to three vergers at regular worship services. His book of French poems "Vergers" was published in 1926. Volunteer vergers are present to offer simple food and drink to all comers. Parish vergers were given the duty of instructing children in reading and in the Catechism. Vergers also assist with tours and special events at the cathedral.
