Exposed to the artist's individual exhibition organized by the Venice Biennale in 1909, together with Porta di Moschea in Brussa and Porta rossa in Anatolia from the collection of Lazzaro G. B., the painting, dated 1869, is part of the series of studies carried out by the artist in Constantinople between 1867 and 1869.In fact, it depicts some sailing ships flying the Turkish flag taken on the Bosphorus strait and brought back to the canvas with a more concise technique than the meticulous one of other studies carried out by the painter. The boats, their reflection on the water, the lively intersection of the trees, the tie rods of the gathered sails and the rope ladders, create an animated vision that stands out against the background of the city, summarized in its profile, and the light of the sky . The main element is the light that seems to break up the color and turn it on in the details of the red Turkish flags moved by the wind.
