 - After the population exchange in the region, churches were made suitable for Muslim worship and began to be used as mosques.
 - It has largely preserved its original plan.
 - While preserving the general plan of the church, changes specific to the mosque were made in the interior.

 - The wooden eaves and roof cladding were reinforced with modern materials while preserving the historical character of the building.
 - The interior has a very simple and spacious design. The wooden ceiling is one of the traditional elements of Ottoman mosque architecture adding a warm atmosphere to the space.
 - The marble mihrab and ornamented minbar emphasize the mosque’s unique Islamic identity. Large chandeliers provide illumination of the space and offer a design that is in keeping with the classical Ottoman mosque interior.
 - Round arched windows both illuminate the space by letting in natural light and complete the architectural aesthetics of the building.
