The Fountain of Ahmed III is a small marble pavilion standing between the gate of Topkapı Palace and the flank of Hagia Sophia, and almost no part of its surface was left plain. It is a square block with rounded corners under five low domes, its deep eaves overhanging the stone like the edge of a tent. Carved tulips, cypresses and vines fill every panel beneath bands of gilded calligraphy, and small bowls of fruit and flowers sit in low relief among the vines. A wall fountain faces each of the four directions.
The verses that ring the pavilion end in the sultan's own words, inviting you to turn the tap, drink, and say a prayer for Ahmed Khan. Grilled kiosks fill the four corners, three windows apiece. The taps are dry now, but the pavilion — finished in 1728, at the height of the Tulip Era — marks the point where Ottoman builders left plain classical lines for curves and dense floral carving.
