Seven hills of Istanbul

Constantinople is known as the City on the Seven Hills (Turkish: Yedi tepeli şehir). The city has inherited this denomination from Byzantine Constantinople which – consciously following the model of Rome – was built on seven hills too.

The seven hills, all located in the area within the walls, first appeared when the valleys of the Golden Horn and the Bosphorus were opened up during the Secondary and Tertiary periods. In the Ottoman Age, as in the earlier Byzantine period, each hill was surmounted by monumental religious buildings (churches under the Byzantines, imperial mosques under the Ottomans).

The first hill on which the ancient city of Byzantium was founded, begins from Seraglio Point and extends over the whole area containing Hagia Sophia, the Sultan Ahmed Mosque and Topkapı Palace.

On the second hill are to be found the Nuruosmaniye Mosque, Grand Bazaar and Column of Constantine. The second hill is divided from the first by a fairly deep valley running from Babiali on the east Eminönü.

The third hill is now occupied by the main buildings of Istanbul University, the Bayezid II Mosque to the south and the Süleymaniye Mosque to the north. The southern slopes of the hill descend to Kumkapi and Langa.
