Four such circuits demand notice.
First came the fortifications which constituted the Acropolis of Byzantium.¹ They are represented by the walls, partly Byzantine and partly Turkish, which cling to the steep sides of the Seraglio plateau at the eastern extremity of the First Hill, and support the Imperial Museum, the Kiosk of Sultan Abdul Medjid, and the Imperial Kitchens.
