Roman Catholic Diocese of Termia

The Diocese of Termia or Diocese of Thermae or Diocese of Thermia (Latin: Dioecesis Thermiensis seu Firminiensis) was a Latin Catholic crusader bishopric located in the Cyclades archipelago in the Aegean Sea. It was originally established as the Diocese of Ceo in 1330, before being renamed in 1600. The diocese was reestablished as a titular see in 1933 under the name Titular Episcopal See of Cea.

History
The diocese in the Cyclades was first established in 1330 as the Diocese of Ceo, part of the Venetian Duchy of Naxos, on the island of Kea. In 1600, the bishopric was moved from Kea to Kythnos, and the diocese was renamed the Diocese of Thermia. Ordinaries of the diocese observed Roman Rite.

In 1650, the Cyclades were conquered by the Ottoman Empire and the diocese's activities were suppressed. The diocese was nominally restored as the Titular Episcopal See of Cea in 1933, and remains listed as such today.
