Many of Ottoman Sultans lived in Topkapi Palace which was classical style and largest palace of Ottoman Empire in Istanbul.

The Palace was constructed with Baroque, Rococo and Neoclassical styles and mixed with traditional Ottoman architecture style. Only six of Ottoman Sultans lived in Dolmabahce Palace.
