First built by Mehmet the Conqueror in the 15th century, this glorious palace beside the Bosphorus was where the sultans of the Ottoman Empire ruled over their dominions up until the 19th century.

 The vast complex is a dazzling display of Islamic art, with opulent courtyards lined with intricate hand-painted tile-work, linking a warren of sumptuously decorated rooms, all bounded by battlemented walls and towers.
