About Histria Citadel
Histria was founded by settlers from Miletus, in Asia Minor, on a peninsula on the western shore of the Black Sea, close to the mouths of the Danube. Ancient tradition dates this to 657–656 BC, though another ancient author gives a later date, around 630 BC. It is the oldest Greek colony on this coast and the first true city on what is now Romanian territory; Herodotus already mentions it in the 5th century BC as a Milesian city near the mouth of the Danube.
For some fourteen centuries the city lived from trade, fishing and the grain of its hinterland, struck its own coins, and was destroyed and rebuilt several times: by the Scythians, by the Getae, then by the Goths, who razed it in 238. The Romans rebuilt it on a much smaller area behind a new wall, and in the 4th–6th centuries Histria was a Christian centre with several basilicas. Sand gradually closed off the bay, the harbour silted up, and in the 7th century, after the Avar and Slav invasions, the city was abandoned.
The ruins were identified in 1868, and Vasile Pârvan began systematic excavations in 1914; archaeological research continues to this day. The former bay is now Lake Sinoe, and the site lies within a nature reserve that is part of the Danube Delta Biosphere Reserve.
What you can see
You enter the city through the Great Gate, flanked by towers, in the late Roman wall of large limestone blocks. Inside, a path leads past the Roman baths, whose brick arches still stand, past the civil basilica with its column bases and the stone-paved square, through the district of shops and on to the 6th-century episcopal basilica. Towards the lake lie the Greek sacred area, with the foundations of the temples of Zeus and Aphrodite, and the district of wealthy late antique houses, with views across Lake Sinoe.
The museum by the entrance, opened in 1982, gathers finds from the site: Greek and Latin inscriptions, pottery, Roman glass, coins, sculpture and architectural fragments, including a marble frieze of the Olympian gods and pieces of the façade of a Hellenistic temple.
Good to know
The site lies in open country with almost no shade: in summer bring water and a hat. The museum and the citadel have separate tickets. In 2026 the museum put out tenders for a fire-suppression system in the museum building and for the renovation of the Pârvan House; no closure to visitors has been announced.

Good to know before you go
- Getting there
By car: from Constanța take the DN22 towards Tulcea, then go through Istria village on the DJ226A to the end of the road: ~66 km, ~1 hour 5 minutes. From Năvodari and Mamaia Nord it is ~38 km (~45 minutes) via Corbu and Istria, and from Tulcea ~92 km (~1 hour 30 minutes) on the DN22.
Public transport: we found no confirmed public transport route to the complex, which lies a few kilometres from Istria village. Without a car, the realistic options are a taxi or an organised excursion from Constanța or the seaside resorts.
