Diocese of Syros

Syren(sis)

The Diocese of Syros (and Milos) is a Latin rite see based on the island of Syros in the Greek Cyclades, historically one of the principal Catholic centers of Greece. Bishop Petros Stefanou, who had led Syros with Milos and Santorini since 13 May 2014, resigned on 11-12 April 2025. The see is vacant, with Archbishop Sevastianos Rossolatos appointed apostolic administrator.

History

Two Greek cities, Syros and Milos, host the Diocese of Syros and Milos (Latin: Dioecesis Syrensis et Milensis). This Latin Church diocese of the Roman Catholic Church forms part of the ecclesiastical province of Naxos, Andros, Tinos and Mykonos.

What is kept by invitation

The record above is published because it is public: what this see is, when it was erected, who holds its chair, and where it stands among its neighbours.

The working record is not. The chancery's address, telephone and email, the clergy of the see, and the hours of Mass, confession and adoration in the parishes within it are kept for members, and a person reads every request.
