Saint Gregory of Nyssa (Greek: Εκκλησία Αγίου Γρηγορίου Νύσσης) was a church and monastery of Trabzon.
It's believed the church was built around 1280-1297 by the wife of John III, Emperor of Trabzon.
Nyssa (current day Nevşehir) is a city located in Cappadocia.
Georgian traveler Timote Gabashvili visited the church in the late 1750s and included this event in his writings.
