The small vestibule, in front of the entrance to the prayer hall, is covered by a small dome. The area above the door, where the ‘kitabe’ (building inscription) should be, shows an empty marble plate. The small pilasters ‘carrying’ the arch are adorned with muqarnas capitals in early-Ottoman style.

Muqarnas is a stalactite-like decoration initiated in Anatolia by the Seljuk (in the 11th – 12th century). They imported it from Iran. Later on it continued to be used in the late-Seljuk architecture of the Beyliks (14th century) and by the Ottomans up to the 19th century.
