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. There can be found there the first Christian Basilica in Romania 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).
