Quick answer
Constanța, Romania’s largest port and oldest continuously inhabited city, sits on the Black Sea coast on the site of ancient Tomis. Founded by Greek colonists and later a major Roman town, it layers classical ruins and faded belle-époque grandeur over a lively modern seaside city.
It is a city of two moods: a historic peninsula of museums, squares and the iconic seafront Casino, and the buzzing resort strip of Mamaia just to the north, with its long sandy beach and summer nightlife. In high season the coast hosts some of Romania’s biggest music festivals, while the old town and seafront promenade reward slower exploration year-round.

Why visit Constanța
Constanța offers a rare mix on the Romanian coast: genuine ancient history as the site of Greek and Roman Tomis, faded seaside elegance around the famous Casino, and a full-on summer beach scene at neighbouring Mamaia. Few cities let you wander a Roman mosaic, photograph an art nouveau landmark and swim in the Black Sea in the same day.
In summer it becomes one of Romania’s liveliest destinations, with major festivals such as Neversea drawing huge crowds. Outside peak season the museums, seafront promenade and historic peninsula make for a quieter but rewarding coastal break with deep classical roots.
