Mainz

The Diocese of Mainz is a diocese of the Catholic Church in Germany, historically known in English by its French name of Mayence. It was created in 1802 with the abolition of the old Archbishopric of Mainz. The diocese is suffragan to the Archdiocese of Freiburg. Its district is located in the states of Rhineland-Palatinate and Hesse. The seat of the diocese is in Mainz at the Cathedral dedicated to Saints Martin and Stephen. The city is famous as the home of the invention of the movable-type printing press, as the first books printed using movable type were manufactured in Mainz by Gutenberg in the early 1450s. Until the twentieth century, Mainz was usually referred to in English as Mayence.
