The functions of the palais du Tau

The palais du Tau is the residence of the archbishop and his administration, such as the chancellery and the officialdom.

What functions do these people perform?

• The archbishop is the head of an ecclesiastical province. In the Middle Ages, he was not only a pastor, but also a "doctor". Under the Ancien Régime, the Church had exclusive responsibility for teaching.
• The chancellor was immediately answerable to the archbishop, for whom he was, in a way, the "keeper of the seals". 
  According to the Code of Canon Law (c. 482), the Chancellor's primary administrative function is to ensure that the acts of the archbishop or bishop (decrees, ordinances, appointments, ordinations, etc., which the Chancellor countersigns) are drawn up (in legal form), signed, dispatched and kept in the curia's archives.
• The Officiality is also known as the "episcopal tribunal". The archbishop is responsible for administering justice in his diocese, ensuring compliance with universal canon law and enacting norms in conformity with it.
