09:00 — Gravensteen. Beat the queues at the Castle of the Counts, the moated 12th-century fortress rising improbably in the city centre. The ramparts give a first panorama of towers and gables; the audio tour is famously witty.
11:00 — The Mystic Lamb. Walk the tower-lined axis to St Bavo's Cathedral, home of the Adoration of the Mystic Lamb by the Van Eyck brothers — the 15th-century altarpiece often called the most influential painting in European art, luminous after its long restoration. Book a timeslot ahead when possible.
13:00 — Lunch on the quays. The Graslei and Korenlei, facing rows of guildhall facades along the River Leie, are made for a terrace lunch. Try Flemish classics: shrimp croquettes, then waterzooi — Ghent's own creamy chicken (or fish) stew.
15:00 — Belfry and St Nicholas. Climb or lift up the UNESCO-listed Belfry for rooftop views over the famous three-tower row; the dragon on its spire is the city's guardian symbol.
17:00 — Boat on the Leie. A short open-boat cruise threads under bridges past merchant houses — the essential low-angle view of the medieval port city.
20:00 — Patershol dinner. The cobbled Patershol quarter, once home of leather workers, is now Ghent's densest cluster of intimate restaurants, from Flemish stews to global kitchens. End with a walk: the illuminated castle and towers after dark are the day's finale.
