The Site and the Excavation Project   

The ruins of an Ancient Greek trade center (emporion) in the heart of Thrace – on the left bank of Maritsa River (ancient Hebros), between the towns of Vetren and Septemvri, were discovered by Prof. M. Domaradzki in 1988. He started regular excavations and in 1990, his team found a stone inscription (known as "Vetren inscription") that helped the scholars identify the site as the Ancient Greek emporion named Pistiros. Merchants from Greek coastal cities of Maroneia, Thassos and Apollonia lived and traded there with their Thracian neighbors under the supreme protection of the Thracian Odrysian kings (the biggest and mightiest Thracian Kingdom at that time). Up to the moment Pistiros is the only certainly identified emporion in the heart of Thrace. That is why excavation of the site are significant source of information for the political, economical and cultural history of the Odrysian kingdom and Thrace in this period.

The emporion was also a major metallurgical center and a key harbor for export of metals and metal products from Thrace to Greece in the Classical and Early Hellenistic periods (from the middle of the 5th to the beginning of the 3rd century BCE). The trade contacts of the emporion are evident through finds of numerous imports such as Attic red-figured and black-slip pottery, amphorae (mainly Thassian) and coins (e.g. several hoards of copper, silver and gold coins found during the excavations - they represent the coinage of different Odrysian kings (e.g. Amatokos I, Bergaios, Kotys I, Amatokos II, Teres II, Kersebleptes, Teres II), Greek cities (Thassos, Maroneia, Parion, Thracian Chersonese, Enos, Apollonia, Messabria etc.) and Macedonian rulers (Philip II, Alexander the Great, Kassandros, Demetrios Poliokretes, Lysimachos etc.).

Most of the ancient authors and the majority of the modern scholars consider the cult of Dionysos rooted in Thrace. Apparently, it played a very important role in the emporion's religious life. For instance the Vetren inscription informs about the oath taken in the name of Dionysos by the Odrysian king: Kotys I (383-359 BCE) and his successor from the citizens of Pistiros - this is how they guaranteed the integrity of their lives, properties and activities in their town under the sovereignty of the Thracian kings.  

Pistiros history in brief:

  • around 500 BCE - Date of the earliest artifacts found on the territory of Pistiros.
  • 475 - 450 BCE - Date of the earliest Attic pottery found at the site - the foundation of Pistiros (like the foundation of the most Greek apoikias elsewhere) was probably preceded by various previous colonial economic and political activities. Greek economic and cultural penetration in the interior of Thrace was intensified after the Persian withdrawal from the Balkans following the battles of Marathon (490 BCE) and Salamis (480 BCE);
  • 450 - 425 BCE - Foundation of the emporion by colonists from the Aegean cities of Maronia, Thassos and Apollonia. Major structures and features of fortification and drainage system were constructed along with tracing and paving of the streets;
  • 370s BCE - Period of significant reconstructions in the emporion during the reign of the Thracian Odrysian king Kotys I;
  • 359 - 357 BCE - Citizens of Pistiros re-contracted their rights and obligations with the successor of Kotys I;
  • 350/345 BCE - The emporion suffered from the invasion of Philip II Macedon in Thrace;
  • 300 BCE - Devastation of Pistiros by the Celts;
  • 278 BCE - Massive invasion of the Celts in the Balkans: Ultimate devastation of the emporion. Afterwards the settlement lost its trading importance and turned into a metal production centre with local importance.         

So far, archaeologists have uncovered the eastern fortification wall of the emporion (having one gate, a tower, and a bastion - all built of stone blocks analogically to the Thassian fortification system), streets paved by stone plates, solid stone foundations of two buildings as well as an efficient drainage system. Buildings of different types are indicating at least two different chronological horizons of the site's existence. The investigation of their characteristic features and shapes, as well as the emporion's planning are among the major research questions concerning Pistiros.


The Field School

The Balkan Heritage Foundation has been conducting an archaeological field school since 2013. In 2024, a Photogrammetry Workshop will be opening that will introduce participants of all backgrounds to digital documentation techniques In the context of the ongoing archaeological research.

Photogrammetry is defined as the art and science of taking measurements from photographs. Over the course of five days, participants will learn how to plan projects, collect data, and process results through a combination of lectures, workshops, and field training with real materials on site and in a laboratory setting. This program will address computational photography and surveying for archaeological excavations starting from the basic optics of digital cameras and surveying instruments to combining these methods together to collect data in the field and process it for various 3D results. By the end of the workshop, participants will be able to contextualize a digital documentation workflow from start to finish.   

The Field School in 2024 Includes the Following Main Topics:

  • Technical Photography for Archaeological Excavations
  • Project Planning
  • Total Station Surveying
  • Terrestrial Photogrammetry
  • Aerial Photogrammetry
  • Photogrammetric Data Processing         

Students who must prepare field reports and presentations for their universities can receive additional instruction and assistance.

All participants will receive:

  • Balkan Heritage Field School Certificate specifying the fieldwork hours educational modules, and sites visited
  • T-shirt.
