Mesimvria-Zone (Zoni) is referred to the ancient colony of Samothraki that was located between Maroneia and Alexandroupolis. Today it is mentioned with two names since it was initially known as Mesimvria but further archeological evidence identified it as Zone.
The city was built in the 7th century BC. It was flourished during the 5th and the 4th century, while there is evidence for its downgrade during the Macedonian and Roman periods.
The physical location and boundaries of the walls determined the final layout of the city. Excavations are taking place since 1966 and they brought to light fortifications, public buildings, and private houses. An extended street network and the sanctuary of Demeter were also among the findings. While the existing temple of Apollo is the only archaic temple in the whole region of Thrace. Finally, the cemetery of the city was found to the west outside of the fortification.
