Kılıç Ali Pasha Complex

The central dome of the mosque is 12.70 metres (41.7 ft) in diameter, carried on pendentives on granite piers and two half-domes on the Qibla axis. Towards the entrance, on two sides, there is a two-storey gallery. The dome is placed at the center with two exedrae rather like a Byzantine basilica, thus the resemblance to Hagia Sophia.[1]

Above the prayer hall are five small domes carried on six marble columns. The tile panels placed high up in the prayer hall are inscribed with ayats (verses) from the Quran. The mosque has only one minaret with one gallery but there are 247 windows including the twenty-four of the central dome. The mihrab is in a square projecting apse.

A 16th-century ship lamp that used to hang from the central dome was removed to the Museum of Ottoman and Turkish Naval History (now the Istanbul Naval Museum/Deniz Müzesi) in 1948.[2]

Two chronograms in the mosque both date it to 988 in the Hijri (Islamic) calendar (1580 in the Julian calendar).

One of the two inscriptions, at the outer entrance of the complex, features a four-verse poem in jali thuluth calligraphic script in Ottoman Turkish by the poet Ulvî and written by calligrapher Demircikulu Yusuf:

Mîr-i bahr â’nî Kılıç Paşa Kapudan-ı zemân

Yaptı çün bu camii ola yeri Darüsselâm
Hâtif-i kudsî görüp Ulvî dedi tarihini

Ehl-i imâna ibâdetgâh olsun bu makam

The letters in the final line - 'May this be a house of worship for people of the faith' - add up to the number 988.

The courtyard contains a marble fountain for ablutions before prayer with eight columns and a dome. The outer porch has a sloping roof supported by twelve columns on the west façade and three at each end, all with rhombus-shaped capitals. In the center a marble portal leads into the mosque.[3]

The graveyard contains the octagonal türbe of Kılıç Ali Pasha with a dome designed by Mimar Sinan. Its wooden doors are inlaid with mother-of-pearl.

Domes of the hamam complex (on the left) and the mosque (on the right)

The medrese, opposite the southeast corner of the mosque, is almost square. It's possible that it was not designed by Mimar Sinan since it doesn't appear in the official list of his works, the Tazkirat-al-Abniya.[3]

To the right of the mosque is the hamam, completed in 1583.[2] The glass doors lead into two separate soğukluks (cool rooms) on either side of the hararet (caldarium - hot room) which is hexagonal in plan with open bathing places in four of its six arched recesses, the other two opening on to the soğukluks. The placement of the soğukluks and the plan of the hararet differ from the usual layout used by Sinan in other surviving hamams.[3]
