Bizim Terkos sözcüğü sanırım oradan geliyor.
İki tane "uzun duvar" var. Birincisi milattan önce 400'lü yıllarda Gelibolu yarım adası üzerine yapılmış ve adı Chersonese [Kırsıniiz] Uzun Duvarı.... Diğeri ise milattan sonra 500'lü yıllarda Marmara Ereğlisi veya Enez kasabası ile Terkos gölü arasına inşa edilmiş... İkincisine Anastasyas Suru adı veriliyor.
The Long Wall was actually a succession of walls on the base of the Thracian Chersonese, the first of which was built in the late 6th century b.c.e. by the Athenian magnate Miltiades the Elder.
Herodotus (The Histories, VI.36.2) reports that "his first act was to wall off the isthmus of the Chersonese from the city of Cardia across to Pactya, so that the Apsinthians would not be able to harm them by invading their land". Herodotus recorded the length of the isthmus as 36 stadia, or approximately 7.2 km.
The exact location of the wall is unknown. The most likely localization is on the isthmus 5 km east of Bulair at the base of the peninsula, which is also its narrowest part and corresponds to the length mentioned by Herodotus and Xenophon. It is however possible that the various walls were built in different locations through the centuries. Thus it has been suggested that the wall of Justinian lay further east, running from the shore of the Propontis near modern Kazan Ağacı north to Ortaköy and thence northwest to the mouths of the river Melas in the Gulf of Saros.
Remnants of walls near Kazan Ağacı and Bolair cannot be definitely linked to the wall, although a trench near Germe Tepe has been proposed as having been part of this fortification line
Gulf of Melas = Enes
Heraklia = Marmara Ereğlisi
Derkon = Terkos
