Sucidava is a late Roman fortress on the Danube at Corabia, which guarded the northern end of Constantine’s Bridge, one of the longest bridges of the ancient world. Its walls and towers, a Roman bath, an early Christian basilica and a “secret well” reached by an underground passage lie on a terrace above the river, and a pier of the bridge survives nearby.

What is there today

On the upper terrace of the Danube stand the defensive walls of the late Roman town (4th–6th centuries) with eight fully exposed towers; the Roman baths, a palaeochristian basilica of the 5th–6th centuries and paved streets have also been found (ro.wikipedia). The fortress’s “secret well” was an engineering feat of its time, meant to keep the garrison supplied with water during a siege (de.wikipedia); Italian Wikipedia describes it as an underground spring running beneath the walls to the outside.

Constantine’s Bridge. About 220 m from the fortress, OpenStreetMap maps the ruins of the Roman bridge. Constantine’s Bridge was opened on 5 July 328 in the emperor’s presence; it was 2,434 m long overall, 1,137 m of it over the riverbed, the longest ancient river bridge, and it stayed in use for about four decades (en.wikipedia). It linked Sucidava with Oescus on the far bank, in today’s Bulgaria (it.wikipedia), and one of its piers can still be seen (de.wikipedia).

History

Sucidava was a main centre of the Getic tribe of the Suci, and in the 2nd and 3rd centuries there was a Roman settlement here (de and ro.wikipedia). It grew from the 270s, and above all after the building of Constantine’s Bridge, whose northern end it protected (en.wikipedia). Coins found here run without a break from Aurelian (270–275) to Theodosius II (408–450). The Huns devastated the town in 443 or 447; it was rebuilt under Justin I or Justinian I, and around 600 the garrison seems to have left (it and ro.wikipedia). Among the finds are 142 published lead seals used to seal goods and documents (de.wikipedia).
