Monuments and historic sites

The Art Nouveau building on the Constanța seafront, opened in 1910, left to decay after 1990 and reopened in 2025 after restoration, with exhibitions on its history and on the Black Sea.

The ruins of the oldest city on Romanian soil, a Greek colony founded by Miletus in the 7th century BC on the shore of Lake Sinoe, with the site museum alongside.

The ruins of the Greek city from which Mangalia grew: the circuit wall with its towers and the Syrian-type basilica on the clifftop promenade, steps from the beach, plus the town's archaeology museum.

Constanța's old town, on the site of ancient Tomis: Ovid Square, the Roman mosaic, the mosque and its minaret, the cathedral, the Genoese Lighthouse and the casino seafront, all a few steps apart.
