The Metropolis of Eleftheroupolis is part of the Church of Greece. It is still unknown when this metropolis was founded, but in an 1886 record by Stylianos Mertzidis there is a reference to an 8th century episcopal throne. Another citation is made in the Vatican library (I.D. Mansi Sanctorum Conciliorum nova et amblissima collection, Vol. XVIIA pp. 373-3760), which has information that under the Patriarch Photios, in the year 879 AD, he and Metropolitan Theodoros of Eleftheroupolis participated in the Eighth Ecumenical Council which was held in Constantinople.
