After the invasion of Trabzon by Sultan Mehmet II in 1461, Sumela Monastery started to have the influence of Turkish art and design in its structure.

This influence can be observed in details such as cupboards, niches on the walls, and the fire-places in the rooms surrounding the courtyard. The pointed arches of the fountain that is collecting the sacred water are reflecting the characteristics of the Turkish architecture as well. 

Another Turkish influence can be observed on some of the paintings on the walls colored with dark red which resembles the brick pointing designs used in 18th century Turkish buildings.
