Scupi

Scupi is an archaeological site located between Zajčev Rid and the Vardar River, several kilometers from the center of modern Skopje in North Macedonia. A Roman military camp was founded here in the second century BC on the site of an older Dardanian settlement. It became later Colonia Flavia Aelia Scupi and many veteran legionnaires were settled there. A Roman town was founded in the time of Domitian and Scupi became the chief center for romanizing Dardania. It was abandoned in AD 518 during interregnum between Anastasius I Dicorus and Justin I after an earthquake destroyed the city.
