One of the most astounding and popular places to visit in Istanbul is Topkapi Palace, the symbolic and political centre of the Ottoman Empire in between the 15th and 19th centuries. It stands on the tip of land where the Golden Horn, the Sea of Marmara and The Bosphorus come together, and is a maze of buildings centered around a series of courtyards, typical of Islamic tradition. Such is the complexity of each building, it will take many hours in order to be explored properly.
