The
Church of Mary is an ancient
Christian cathedral dedicated to the
Theotokos ("Birth-Giver of God",
i.e., the
Virgin Mary), located in
Ephesus (near present-day
Selçuk in
Turkey). It is also known as the
Church of the Councils because two councils of importance to the history of
Early Christianity are assumed to have been held within. The church is located in the south stoa of the Olympieion (Temple of Hadrian Olympios) next to the harbor of Ephesus.
