What is it?

Thessaloniki is Greece's second city and its undisputed capital of food, music and late nights — a place where 2,300 years of history are stacked casually on top of one another. Founded in 315 BC and named after Alexander the Great's half-sister, it became a Roman metropolis, a glittering Byzantine second city, an Ottoman port and, for centuries, the 'Mother of Israel', home to one of Europe's greatest Sephardic Jewish communities. Wander and you'll pass the 4th-century Rotunda with its shimmering gold mosaics, the Arch of Galerius rising from a busy pedestrian street, and fifteen UNESCO-listed Paleochristian and Byzantine monuments hiding in plain sight between kebab shops and record stores. The city smells of coffee, charcoal-grilled souvlaki and warm bougatsa; it sounds like rembetiko drifting from a tsipouro bar in Ladadika and the clatter of the Kapani market at noon. Above it all, the whitewashed lanes of Ano Poli — the Upper Town that survived the great fire of 1917 — spill down from the Byzantine walls toward a curving bay where, on clear winter days, Mount Olympus floats on the horizon.

Where is it?

Thessaloniki sits at the head of the Thermaic Gulf in Macedonia, northern Greece, roughly five hours by road or train from Athens and served by Makedonia Airport (SKG) with direct flights across Europe. Base yourself near Aristotelous Square, Ladadika or Valaoritou for nightlife, or Ano Poli for views; the Nea Paralia waterfront promenade and the White Tower are the natural starting points for any visit. Come in May–June or September–October for warm sea air without August's heat, or in November for the Thessaloniki International Film Festival, when the whole city turns cinephile.

What makes it worth it?

Visitors arrive expecting a stopover and leave plotting their return — Thessaloniki has a way of getting under your skin. It's a city that doesn't perform for tourists: the tavernas are full of locals, the student population keeps the bars honest and cheap, and nobody rushes you off a table you've occupied for three hours. 'The best food in Greece' is the line you'll hear most often, and after a night of tsipouro and mezedes that keep arriving unbidden, you'll probably agree. There's emotional weight here too — standing in the Rotunda, or reading the memorial to the 50,000 Jewish citizens deported in 1943, you feel the layers of Europe's history pressing close. Years later what you'll remember is a specific sunset: sitting on the seafront steps with a beer, the Umbrellas sculpture silhouetted against pink water, Olympus glowing in the distance, and the sense that you'd stumbled onto a city Greece had been keeping to itself.

How accessible is it?

Very easy — Thessaloniki is a flat, compact, walkable city where almost everything of interest lies within a 30-minute stroll of the White Tower, and its new metro (opened 2024) makes crossing town effortless. Budget travellers can manage on €50–70 a day including a hostel bed, souvlaki lunches and museum entries; mid-range visitors should plan €100–180 a day for a central hotel, taverna dinners and drinks. Museum tickets run €4–10 (the Archaeological Museum, Museum of Byzantine Culture and Rotunda are the essentials), and most churches are free. No booking is required for day-to-day sightseeing, though hotels fill fast during the November film festival and the September Trade Fair. EU citizens need no visa; most other nationalities enter under Schengen rules. Day trips are simple: Vergina's royal tombs of Philip II, the beaches of Halkidiki, and Mount Olympus are all within 1–2 hours by bus or hire car.
