Church of St. Thanas has been a very old church in this area, various documents mention as such, but say it is not known when the first foundations are laid, but we can say with certainty that the foundation of this church are throwing more before Turkish rule. In hummocks that lie behind this church until Mborja lies near an area of archaeological whole set of late antiquity and the medieval cite this as chroniclers travelers centuries and also elderly and mborjarë Korças who assert the existence The ruins in the area.
Archaeologists have discovered Korca and antique baths 6th century mosaic snippets, etc. Roman graves. As well as the decree of Sultan Bayezid second at the end of the 15th century that speaks of delimitation of property that do Mirahorit Iliaz mentioned in this area a wall fastening, a slab of stuck. Also interesting in this document is referred to a small grove situated on a hillock in the vineyards that is lower after which receives direction from Emboria. Historically known that the only grove of trees in the middle of vineyards located on a hillock in the area of hills and it was St. Thanas, but the document does not mention completely, as in the document as the sultan had apparently not mention the name of a church.So again we can say that the Church of St. Thanas must be very old, before Turkish.
We documents with complete and accurate so far available, such as the nearly 400-year-old codex of Korca Metropolis appears that this church was first built on the hill and out of toponym formed as Tidewater St. Thanas. It should be mentioned that in this period the Turks did not allow Christians to build new churches but only repairs of the old and those with special ferman and therefore it can be said, that this church was built so the Turkish invasion.
