Stand on Ovid's Square in the old town and you are standing on layers: the Roman poet's statue in front of you, the National History and Archaeology Museum behind it in the old City Hall, and beneath the pavement the remains of ancient Tomis. Constanța has been continuously inhabited for a very long time, and the peninsular quarter is where that shows most clearly.
The city suits travellers who want a walkable historic core, a seafront promenade, and museums that reward a slow hour rather than a rushed one. It also works well for families, thanks to the shallow water at the Modern beach and the Natural Sciences Museum Complex.
This guide covers the main sights in and around the old town and the seafront, with practical notes on timing and what to pair with what.
Top things to do in Constanța
1. Old Casino Constanța
The Art Nouveau casino on the seashore was conceived by architects Petre Antonescu and Daniel Renard and opened in 1911. It is a historic monument and a symbol of the modern city, and it has been abandoned for a long time, with renovation of the building finally beginning in 2021.
Come for the building and the surrounding promenade rather than for anything inside. The Constanța Aquarium is nearby, so the two combine naturally into one seafront stop.
2. Statue of Ovid
The statue by Ettore Ferrari was erected in 1887 after a public subscription, and it gave its name to Ovid's Square in the old town. Ovid was sent into exile here by Augustus and wrote his Tristia in Tomis.
The statue stands in front of the National History and Archaeology Museum, which is housed in the old City Hall, so you can see both without moving far. Look for the square as your anchor point when you start exploring the peninsula.
3. Roman Mosaic Edifice (Edificiul Roman cu Mozaic)
Utility work in Ovidiu Square in 1959 uncovered one of the most important monuments of ancient Tomis. The complex was built in three terraces and connected the city with the ancient port, with a monumental building erected in the 4th century AD, probably under Emperor Constantine the Great. Of the original mosaic area, about 700 m² still remains.
Because it sits right by Ovidiu Square, it fits neatly between the Statue of Ovid and the National History and Archaeology Museum. Give yourself time to read the remains rather than walking past them.
4. National Museum of History and Archeology
On Piata Ovidiu, the museum displays an impressive collection of pieces from Greek and Roman antiquity, including the Glykon Snake, Fortuna and Pontos, Two-faced Nemesis and countless amphoras. Outside the museum there are marble tombs and artifacts as well.
It is the natural companion to the Roman Mosaic Edifice and the Statue of Ovid, all within the same square. In summer it opens daily, while in the colder months it opens Wednesday to Sunday, so plan the day of your visit accordingly.
5. Grand Mosque of Constanța (Marea Moschee din Constanța)
On Strada Crângului, a stone's throw from Ovidiu Square, this was the first public building made of concrete in Romania, a gift from King Carol I to the local Muslim community. It is built in Moorish style in honour of Sultan Mohamed II, and it hosts a carpet brought in 1965 from the island of Ada Kaleh.
Its position near Ovidiu Square makes it an easy addition to a walk through the old town. Pair it with the square and the mosaic rather than making a separate trip.
6. The Natural Sciences Museum Complex
The complex is an important reference for the cultural and scientific image of the city and a big part of the summer offer on the Romanian seacoast. It consists of several parts: the Dolphinarium, the Planetarium, the Exotic Birds Exhibition, the Micro Delta and the Aquarium.
The Dolphinarium organises shows in an amphitheatre with a pool, featuring dolphins and seals from the South Atlantic, and the Planetarium runs its own show schedule. Because the shows run at set hours, check the times for the day you plan to visit and build the rest of your day around them.
7. The Aquarium
The Aquarium presents permanent aquatic flora and fauna in 57 tanks, with a collection made up entirely of living organisms, alongside naturalized collections of marine and freshwater fish and invertebrates. Its exhibition patrimony covers over 100 species.
It sits near the Old Casino Constanța on the seafront, which makes it a good indoor counterpart to a promenade. It is a straightforward stop if you are travelling with children.
8. Genoese Lighthouse (Farul Genovez)
The lighthouse stands behind the statue of Eminescu on the sea front, at the southeast corner of the Tomitane Peninsula. Although it was built by an English company, it is called the Genoese Lighthouse in memory of the merchants' lighthouse that stood before it, and its last period of operation ended in 1913.
It belongs to the Sea's Museum and sits on the seafront, so combine it with a walk along the coast rather than treating it as a separate outing.
9. Marine Museum (Muzeul Marinei)
On Traian Street, the museum holds casts after epigraphic documents, coins, art works and original articles of significant historical value: anchors, amphorae, dozens of models reproducing vessels of the Romanian Navy, navigation instruments, documents and photographs, fire arms, propellers, lighthouse lenses, flags and paintings.
It is a natural pairing with the Genoese Lighthouse and the seafront, since both deal with the same maritime history. Opening hours differ between summer and winter, so check before you go.
10. Cathedral of Saints Peter and Paul
The Cathedral of Saints Peter and Paul was built between 1883 and 1885. It is one of the landmarks of the old town and fits easily into a walking route through the peninsula.
Include it as a pause on your walk between the square and the seafront rather than as a destination on its own.
11. Hünkar Mosque (Geamia Hunchiar)
The Hünkar Mosque was completed in 1869, making it one of the older religious buildings you can see in the city. It adds to the multicultural thread that runs through Constanța's history.
Visit it as part of the same old-town walk that takes in the Grand Mosque of Constanța, so you can see the two together.
12. The Popular Art Museum
On Aristide Karatzali Street, the Popular Art Museum keeps summer and winter opening hours, opening later in the summer and closing earlier in the winter.
It is a good choice for a slower hour in the old town, and it can be slotted in between the square and the mosques.
13. The Ion Jalea Sculpture Museum
On Arhiepiscopiei Street, the museum is arranged in a building built in the interwar period by architect C. Pariano in Brancoveanu style. It shows more than 120 works in bronze and plaster donated by the artist Ion Jalea to his hometown.
It is a compact stop, so pair it with the rest of your old-town walking route rather than planning a trip around it.
14. The Archaeological Park
Right in the centre of the city, the Archaeological Park is a pleasant place for a walk if you are in the area. It works as a breather between museum visits.
Use it to break up a day of indoor sights, especially in the warmer months.
15. The beach
You can sunbathe or swim in the Black Sea, and there is a large beach called Modern right in the middle of the city, near the marina, which is favoured by locals. The water is very shallow, so it suits taking children to play safely.
The best beaches are in the Mamaia resort in the north part of Constanța, with several kilometres of sandy beaches and no rocks. In the off season, from September to April, the same stretch is good for walks and photographs. If you arrive by car not registered in Constanța County between May or June and September, expect to pay an entrance fee at the ticket booth.
If you only have one day
Morning: Start at Ovid's Square, where you can see the Statue of Ovid and then step into the National Museum of History and Archeology in the old City Hall. From there, visit the Roman Mosaic Edifice, which was discovered during work in the same square.
Afternoon: Walk to the Grand Mosque of Constanța on Strada Crângului, a stone's throw from the square, then continue through the old town to the Cathedral of Saints Peter and Paul and the Hünkar Mosque. If time allows, add the Popular Art Museum or the Ion Jalea Sculpture Museum.
Evening: Head to the seafront for the Old Casino Constanța and the surrounding promenade, then walk to the Genoese Lighthouse behind the statue of Eminescu. If you still have energy, the Aquarium is nearby.

Is the beach suitable for children?
Yes. The large beach called Modern, right in the middle of the city near the marina, has very shallow water, so children can play safely. The beaches in the Mamaia resort to the north are sandy with no rocks.
Do I need to pay to bring a car into Mamaia?
If you arrive by car not registered in Constanța County between May or June and September, expect to pay an entrance fee at the entrance ticket booth. Parking lots with a fee are guarded, and free parking is the smaller share of what is available.
What can I see near Ovid's Square without travelling far?
The Statue of Ovid stands in front of the National History and Archaeology Museum, the Roman Mosaic Edifice was discovered during utility work in the square, and the Grand Mosque of Constanța is a stone's throw away.
