On the picture: The upper part of the marble ‘Taşkapı’ (monumental main entrance) in late-Seljuk style. The elegant arabesques and floral motifs of the large panels on the left and the right of the muqarnas (stalactite) vaulting announce the later Classical Ottoman style.
Above the door a long and elaborate building inscription (82 x 342 cm) gives the name of its initiator: ‘Sultan oğlu Sultan Mehmed bin Bâyezid bin Murad bin Orhan’ = “Sultan’s son Sultan Mehmed, son of Bâyezid (who was) son of Murad, (who was) son of Orhan”, and (among praises and other detailed information) the date the building works finished: 822 H. (= 1419).
The entrance door is flanked by two mihrab-like niches; above them other inscriptions (82 x 129 cm) give more details about the mosque. The inscription on the left names the architect: “Hacı Ivaz bin Ahi Bâyezid” (Hacı Ivaz son of Ahi Bâyezid), who was also an army commander and a vizier.
