Thessaloniki Travel Guide: Greece’s Second City, Food & Byzantine Heritage
Thessaloniki is the city Greeks love to debate. Athens claims the history, but Thessaloniki has the soul. Greece’s second city sits on the Thermaic Gulf, a sprawling port city that has been a crossroads of civilisations for over 2,300 years — Romans, Byzantines, Ottomans, and Jews have all left their mark. The result is a city that feels less like a tourist destination and more like a real place where people live, eat, argue, and celebrate with an intensity that catches visitors off guard. The food scene is the best in Greece. The nightlife starts at midnight. And the Byzantine churches, Roman rotunda, and Ottoman mosques testify to a layered history that rivals any city in Europe. This is Greece’s best-kept secret — and locals will happily tell you they prefer it to Athens.
A Brief History of Thessaloniki
Thessaloniki was founded in 315 BC by Cassander, a general of Alexander the Great, who named it after his wife — Alexander’s half-sister. It flourished under the Roman Empire as a key stop on the Via Egnatia (the Roman road connecting Rome to Constantinople). The Apostle Paul preached here and wrote two epistles to the Thessalonians. Under the Byzantine Empire, it was the second most important city after Constantinople, with magnificent churches built between the 4th and 14th centuries. The Ottomans conquered it in 1430 and brought a new layer — baths, mosques, and hamams. In 1917, a great fire destroyed much of the old city, which was rebuilt in a European style. The Jewish community, once half the city’s population, was devastated in the Holocaust. The 20th century brought waves of refugees from Asia Minor, giving the city its distinctive Anatolian character. Today, Thessaloniki is a modern, progressive, proudly multicultural city that wears its history lightly.

Top Attractions in Thessaloniki
1. The White Tower
The White Tower is Thessaloniki’s most recognisable landmark — a 33.5-metre cylindrical Ottoman tower on the waterfront that has become the symbol of the city. Built in the 15th century, it was part of the city’s fortifications and served as a garrison, a prison, and (infamously) the scene of the 1826 massacre when Ottoman troops executed Janissary rebels. The tower was whitewashed in 1890, lending it its current name. Today, it houses a modest but interesting museum on the history of Thessaloniki (€6, open Tuesday–Sunday). The top offers a fine 360-degree view over the harbour and the city stretching to Mount Olympus on clear days.
Hours: Tuesday–Sunday 9:00–16:00 (winter), 9:00–19:00 (summer)
Cost: €6
Best time: Late afternoon for the golden light over the gulf
2. Byzantine Churches & Rotunda
Thessaloniki has more UNESCO-listed early Christian and Byzantine monuments than any other city in Greece. The Rotunda, built by Emperor Galerius in 306 AD as his mausoleum (he never used it), was turned into a church and then a mosque — its minaret survives. The interior mosaics, glittering with gold leaf, are among the finest in the Balkans. The Church of Agios Dimitrios, the city’s patron saint, is the largest church in Greece and contains the saint’s crypt, said to flow with myrrh. The Church of Agia Sofia (a smaller version of Constantinople’s Hagia Sophia) and the Church of the Acheiropoietos (one of the earliest surviving churches in the world, circa 450 AD) are all within walking distance of each other.
Rotunda: €6 (included in €15 combined ticket for 4 Byzantine monuments)
Agios Dimitrios: Free (crypt €2)
Best for: History lovers, mosaic admirers, anyone interested in Byzantine art
3. Thessaloniki Food Scene
Thessaloniki is widely considered the food capital of Greece. The city’s cuisine is influenced by its multicultural history — refugees from Asia Minor, Pontus, and Constantinople brought their culinary traditions, creating a food culture that’s distinct from southern Greece. Start the day with bougatsa — a warm filo pie filled with creamy custard, cheese, or minced meat, dusted with cinnamon and sugar, from a bakery like Bougatsa Bantis (open since 1929). For lunch, head to the Modiano Market (currently under renovation in 2026 but still partially open) or the Kapani Market for meze — small sharing plates like tyrokafteri (spicy cheese dip), saganaki (fried cheese), and grilled octopus. Dinner at a traditional taverna means ouzo or tsipouro, meze, live music, and conversations that last until 1 AM.
Best bougatsa: Bougatsa Bantis on Pavlou Mela Street — €3, open from 6 AM
Best taverna area: Ladadika district (the old port) — €12–18 per person
Street food must-try: Gyros from one of the shops on Egnatia Street (€3–4)
4. Ano Poli & Byzantine Walls
Ano Poli (Upper City) is the oldest surviving neighbourhood of Thessaloniki — the only part of the upper city that survived the 1917 fire. It’s a maze of narrow, winding streets, traditional Macedonian houses with overhanging balconies, hidden Byzantine churches, and incredible views over the city and the gulf. The Byzantine walls, built in the 4th century and fortified over the centuries, encircle the upper city and are free to walk. The Heptapyrgion (Seven Towers) fortress at the top was used as a prison until the 1980s, feared by Greek dissidents. The walk from the church of Agios Nikolaos Orfanos to the walls, then along the ramparts to the Trigonion Tower, is the best walking route in Thessaloniki.
Location: Walk from the city centre uphill via Olympos Street (20 minutes)
Walls access: Free, open 24/7
Best time: Sunset for the view over the gulf
5. Archaeological Museum
Thessaloniki’s Archaeological Museum is one of the best in Greece — modern, well-curated, and far less crowded than Athens’ National Archaeological Museum. The star attraction is the Derveni Krater, a stunning 4th-century BC bronze volute krater (wine-mixing vessel) found in a nearby tomb, decorated with figures of Dionysus and his followers. The museum’s gold collection includes exquisite Macedonian jewellery, wreaths, and ceremonial armour from the royal tombs at Vergina (a world-class site that’s a 1-hour bus ride from Thessaloniki). The “Thessaloniki in Antiquity” section brings the city’s Hellenistic and Roman history to life with everyday objects — glassware, pottery, and even ancient surgical instruments.
Hours: Tuesday–Saturday 9:00–16:00, Sunday 9:00–15:00
Cost: €8
Time needed: 2 hours minimum
6. Waterfront & Aristotelous Square
Thessaloniki’s waterfront is one of the great urban promenades of Europe — 3.5 kilometres of uninterrupted pedestrian walkway from the White Tower to the Concert Hall. The Nea Paralia (New Waterfront) was completely redesigned in the 2010s with themed gardens, public art, bicycle lanes, and carefully designed seating areas. It’s where the city comes to stroll at sunset, jog in the morning, and socialise in the evening. Aristotelous Square, the main square of Thessaloniki, is one of the most beautiful squares in Greece — a grand 1920s ensemble of arcaded buildings designed by French architect Ernest Hébrard, leading the eye down to the Thermaic Gulf. The cafés on the square’s eastern side serve the best people-watching in northern Greece.
Waterfront length: 3.5 km from White Tower to Megaro Mousikis (Concert Hall)
Best sunset spot: The pier just east of the White Tower
Aristotelous best view: The upper arcades at number 8, looking down to the sea
Disclaimer: The Rotunda may close unexpectedly for renovations. Modiano Market is partially closed for restoration work in 2026. Vergina Royal Tombs archaeological site is 1 hour from Thessaloniki by KTEL bus — check return schedules before you go.
