What is "sucidava"

Sucidava (Sykibid after Procopius, Σucidava after Pârvan, where Σ is pronounced "sh") is a Dacian and Daco-Roman historical site, situated in Corabia, Romania, on the north bank of the Danube. The first Christian Basilica established in Romania can be found there and the foot of a Roman bridge over the Danube built by Constantine the Great to link Sucidava with Oescus (today in Bulgaria, in Moesia). There is also a secret underground fountain which flows under the walls of the town to a water spring situated outside.

From an archaeological point of view, the coins found at Sucidava show an uninterrupted series from Aurelian (270-275) to Theodosius II (408-450). The archaeological evidence show that in AD 443 or 447 the city was sacked by the Huns, and was restored under Justin I 518-527 or Justinian I 527-565. Around 600, it seems that the Roman garrison abandoned the city.
