Parthicopolis was an Ancient Roman city located in the Roman province of Macedonia; its ruins can be found in the downtown of today’s Sandanski in Southwestern Bulgaria.
It is known to have been an important center of early Christianity, having been located just some 100 km away from the Ancient Greek town of Philippi where Apostle Paul established the first Christian community in Europe.
A testimony for the significance of Parthicopolis as an Early Christian center is the fact that it was mentioned during the Nicaea Council. The town of Parthicopolis was destroyed in barbarian invasions, possibly by the Slavs who tried to capture Thessaloniki in the second half of the 6th century.
