Kılıç Ali Paşa Hamamı was commissioned by a man who began life as a fisherman's son in Calabria, was seized by corsairs, and rose to command the entire Ottoman navy. For his bath the aging admiral hired Mimar Sinan, the empire's master architect, already near ninety when he raised the single vast dome over the hot room in the 1580s. It stood among the mosque, school and tomb of the admiral's complex at Tophane, on ground he is said to have won back from the shore. Built to wash the sultan's sailors, it is one of Sinan's few surviving baths, and its dome ranks among the widest any single Istanbul hammam ever received.
A long restoration returned it to working life in 2012, and it steams still. You undress beneath the tall wooden galleries of the camekan, then pass into marble warmth where daylight falls in coins through thick glass set in the dome. At the centre, heat rises from the broad göbek taşı, the platform where bathers lie until the steam opens the skin. One quirk of its single chamber: men and women bathe in separate sessions, never together.
