Constanţa is Romania's main Black Sea port, built on a headland with the old town at its tip and the modern city spreading inland. The resort strip at Mamaia runs north along a sandbar between the sea and a lagoon.
The Roman mosaic building near the harbour preserves an enormous floor from the ancient port of Tomis, and the archaeological museum beside it is substantial. The poet Ovid was exiled here and is commemorated in the square that bears his name, the casino on the seafront is a decaying art nouveau landmark, and the Danube Delta lies north.
The old town is walkable and buses cover the city and the resort strip. Trains reach Bucharest in around two hours.
Summer is the beach season and is warm and busy along Mamaia. Late spring and early autumn are quieter, and winters are cold and windy on this coast.
Romania uses the RON, calling code +40.
Romania uses the leu rather than the euro, and Romanian is the everyday language with English spoken by younger people. Cards are accepted almost everywhere.
