Local goldsmiths used gold and silver to produce typical Thracian plate armour, ceremonial ornaments for the horses of the kings and the aristocracy, as well as valuable pateras and ritons.
Despite ethnic diversity, numerous internal and external conflicts, and cultural differences, the populations of North-Eastern Bulgaria and the cities along the seashore have demonstrated stable tolerance to each other.
All over North-East Bulgaria and even near Odessos were found a significant number of bronze items with Celtic ornaments and typical weapons, all quickly adopted by Thracians.
Varna, historically known as Odessos, grew from a Thracian seaside settlement to a major seaport on the Black Sea.
Varna is an important centre for business, transportation, education, tourism, entertainment, healthcare.
Theophanes the Confessor first mentioned the name Varna, as the city came to be known with the Slavic conquest of the Balkans in the 6th to 7th century.
The name could be of Varangian origin, as Varangians had been crossing the Black Sea for many years, reaching Constantinople in the early Middle Ages.
The latter is often said to be of Carian origin, though no modern scholarship supports this.
