Seven Hills Hotel near Topkapi Palace Istanbul is undoubtedly one of the most important of Istanbul's many historical structures. It was one of the first buildings constructed after the Turkish conquest of the city and it was the uninterrupted seat of the Ottoman Empire until the building of Dolmabahce Palace in 1856.
Immediately after conquest of the city in 1453, Mehmed the Conqueror had a palace built for him in what is now the district called Fatih. This turned out to be too small however and so he began the construction of Topkapi, the first stage of which lasted from 1472 to 1478. The palace was built around four courtyards leading one into the next.
