Municipality
The present municipality of Thera (officially: "Thira", Greek: Δήμος Θήρας), which covers all settlements on the islands of Santorini and Therasia, was formed at the 2011 local government reform, by the merger of the former Oia and Thera municipalities.
Oia is now called a Κοινότητα (commune), within the municipality of Thera, and it comprises the local subdivisions (Greek: τοπικό διαμέρισμα) of Therasia and Oia.
The municipality of Thera includes an additional 12 local subdivisions on Santorini island: Akrotiri, Emporio, Episkopis Gonia, Exo Gonia, Imerovigli, Karterados, Megalohori, Mesaria, Pyrgos Kallistis, Thera (the seat of the municipality), Vothon, and Vourvoulos.
