The St. Paraskeva Church (Greek: Ιερός Ναός Αγίας Παρασκευής) is a Greek Orthodox church in the town of Giannitsa, in northern Greece, dedicated to Saint Paraskeva of the Balkans, and belonging to the archdiocese of Edessa, Pella and Almopia [el].

[1][2][3] It was originally an Ottoman mosque that was converted into a church following the incorporation of Giannitsa and the rest of Greek Macedonia into Greece in the early twentienth century.

The building was originally built as a Muslim mosque built in the fifteenth century, probably by one of the descendants of Gazi Evrenos, the founder of Giannitsa,[4] and described by Ottoman traveller and explorer Evliya Çelebi as a mosque made of large stones.

[6] In 1947-1948, Archimandrite Nicander Papaioannou, the owner of the plot and the building, turned the mosque into a church.

The church then functioned as a monastery for about forty years with the appropriate utility rooms and lodgings.
