Thessaloniki

Thessaloniki runs on a late Mediterranean rhythm — cafés on Aristotelous Square fill by noon and stay full until midnight, the waterfront promenade along Nikis Avenue draws a constant procession of locals rather than tour groups, and the city's commercial energy belongs entirely to its own residents. Roman ruins sit inside shopping streets without barriers or fanfare: the Arch of Galerius interrupts a pedestrian retail corridor, and the Rotunda stands a short walk from both, its mosaic fragments still visible through restoration scaffolding. The Byzantine churches — around 15 UNESCO-listed sites within the city limits — are working parishes, not museum pieces, and the Ano Poli district above the modern center preserves Ottoman-era timber houses and a pace that the lower city has mostly abandoned. Luxury retail and international chain infrastructure are thin on the ground; the city's commercial identity runs through indoor markets like Modiano and Kapani, where the transaction is still between a vendor and a regular.
