Anastasian Wall
The Anastasius Wall, built by the Byzantine emperor Anastasios I (reigned 491-518), extends from the Black Sea to the Marmara Sea to protect Istanbul against raids from the Thracian direction. The walls start from the place called Evcik İskelesi on the Black Sea coast and after extending west for 500 meters, it turns southwest and reaches Hisartepe. From there, it passes near Karacaköy, crosses Balçıkdere and Karacaköy Stream, crosses Hamzaderesi and reaches the small Kuşkaya Hill. The city walls extending 0.5 km south of this hill lead to Hızırtepe and from there parallel to the Kabakça-Karacaköy road and continue south along the Kurfallı-Gümüşpınar road. It is reported that only the remains of the foundations of the city walls can be seen after Hırsıztepe. The traces of the city walls pass through Kurfallı and reach Çilingirtepe, leaving the Kurfallı-Silivri road to the east. From here, the long wall of Anastasios follows the Kurfallı-Fener road, 200 meters west of Fener and leaving Yapağca to the east, passing through Parapattepe to Sancaktepe and from there to the sea on the Marmara coast at Karınca Cape.
