Several kilometres north of the city is the Valley of the Thracian Rulers where many magnificent royal tombs are located.
Seuthopolis was not a true polis, but rather the seat of Seuthes and his court. His palace had a dual role, functioning also as a sanctuary of the Cabeiri, the gods of Samothrace. Most of the space within the city was occupied not by homes but by official structures, the majority of the people living outside the city. It had Thracian and Greek populace. In 281 BC it was sacked by Celts.
The dual role of Seuthes' palace (royal court and sanctuary) indicates that Seuthes was a priest–king: the high priest of the Cabeiri among the Odrysian Thracians. According to Seuthopolis’ sign, sanctuary of Dionysius/Sabazios was situated on the square.
The cemetery of Seuthopolis included a number of brick tholos tombs, some covered by tumuli, in which the upper-class were interred, sometimes along with their horses. The less affluent were cremated, with modest grave goods laid alongside.
The ruins of the city were discovered and excavated in 1948 by Bulgarian archeologists during the construction of the Georgi Dimitrov (later renamed Koprinka) Reservoir. However, it was decided to continue with the construction and flood the dam, leaving Seuthopolis at its bottom.
One of the most important archaeological finds is the so-called "Great inscription" found in 1953 in the palace-citadel.
In 2005, Bulgarian architect Zheko Tilev proposed a project to uncover, preserve and reconstruct the city of Seuthopolis (the best preserved Thracian city in Bulgaria) by means of a dam wall surrounding the ruins in the middle of the dam, enabling the site's inscription as a UNESCO World Heritage Site and making it a tourist destination of world importance. Tourists would be transported to the site by boats. The round wall, 420 metres in diameter, would enable visitors to see the city from 20 metres above and would also feature "hanging gardens", glass lifts, a quay, restaurants, cafés, shops, ateliers, etc. It would be illuminated at night.

- The Princeton Encyclopedia of Classical Sites (eds. Richard Stillwell, William L. MacDonald, Marian Holland McAllister),A Thracian city near the village of Koprinka. It was founded at the end of the 4th c. B.C. by Seuthes III. The large quantity of material discovered during the excavation has shown that Seuthopolis was not only a center of production, but also of commerce. The city rises on a terrace circumscribed on three sides by the Tundza and by one of its tributaries. It was a fortified city of ca. 5 ha with a pentagonal circuit wall 2 m thick and 890 m in perimeter, with a quadrangular tower at each angle. At the N, between two towers, is the principal gate; and at the south are two gates between bastions. The wall is constructed of clay bricks and wood on stone foundations. The city's orthogonal plan is regular, with two large arteries that lead from the gates to the center. The agora is in the NW sector. In the NE zone is a walled and towered trapezoidal area within which is enclosed the palace of the prince and the Sanctuary of the Great Gods of Samothrace. In the houses, which are built with rooms around a court, has been found a type of plaster. Elements of porticos have been found and upper galleries of wood. The houses were furnished with wells and drainage systems with a channel in the center of the street. The influence of Hippodamos is evident, though the democratic distribution of living quarters is lacking. Seuthes III built his city on the site of an earlier settlement, and he also followed the Hellenistic fashion of the Diadochi in giving it his own name. Greek influence is prevalent in the urban elements cited and in decoration such as antefixes, stucco, and incrustation, and in the use of the Doric capital
