 - The mosque has a narthex, which was later closed with wooden walls. There are a total of thirteen windows arranged on top of each other on the northern facade where the main door is located.
 - The minaret located in the northwest corner has a square base and a polygonal section. The fine muqarnas under the minaret balcony are an elegant example of classical Ottoman stonework.
 - The interior has a wooden ceiling with bars, and according to Evliya Çelebi, the roof of the mosque was once covered with lead.
 - The windows in the Harim section and the hand-drawn works on the door are elegant examples of Ottoman art. There is an Arabic inscription consisting of three couplets written in Thuluth calligraphy on the door.
