Everyone photographs the white walls. Fewer people know that the whiteness is epidemiological — lime kills bacteria, and the annual lime-washing of Ostuni's walls has been a public health measure since the 14th century. This is the guide to the White City that explains what you're actually looking at.
Read the guide →Every article about Ostuni says "the White City" and shows a photograph of whitewashed walls against a blue sky. What they don't say: the white lime wash (calce viva) applied to the walls of the old town has been renewed annually since the medieval period, originally for sanitary reasons — lime kills bacteria, which mattered in a dense hilltown before modern sanitation. The whiteness of Ostuni isn't decorative. It's epidemiological. The Pugliese hill towns used the same technique across the Valle d'Itria for the same reason. Ostuni just has the most dramatic topography.
The centro storico of Ostuni occupies a hill 218m above sea level, 8km from the Adriatic coast. The cathedral (Cattedrale di Santa Maria Assunta) at the top was begun in 1435 in Flamboyant Gothic style — unusual in Puglia, which typically favours Romanesque or Baroque. The rose window (1476) on the cathedral facade is one of the finest in southern Italy. Entry free; the attached diocesan museum (Museo Diocesano, €3) has a remarkable collection of pre-Christian artifacts including a Messapian Bronze Age collection.
The old town is walkable in 2–3 hours at a thorough pace. The key streets: Via Cattedrale (the main climb from the new town), Largo Lippolis (the belvedere with the best views toward the coast), and the network of vicoli descending from the cathedral toward the valley — quieter, more residential, and more authentic than the main tourist route.
The most important thing nobody tells you about visiting Ostuni: go at 7pm, not midday. The whitewashed walls catch the golden hour light differently than any other time — the shadows turn blue while the lit surfaces go amber. The tourist crowds thin after 6pm. The residents come out for the passeggiata. The bars open. This is when Ostuni works.
Ostuni sits in the Brindisi province, between the Valle d'Itria trulli zone and the Adriatic coast. Its food reflects both: the olive oil is from ancient Ogliarola trees (some over 2,000 years old in the surrounding countryside), the vegetables come from the Adriatic hinterland, and the seafood arrives from Brindisi port 40km south. The specific Ostunese specialty: carne podolica — beef from the Podolica cattle breed, which grazes on the rough garrigue of the Murge plateau. The meat is lean, intensely flavoured, and available at Ostuni butchers at €15–25/kg (significantly cheaper than Chianina in Tuscany for comparable quality).
Where to eat in Ostuni's old town: Osteria del Tempo Perso (Via G. Tanzarella Vitale 47) — cave restaurant in the old town, lunch and dinner, Pugliese classics at €35–45 per person. La Cava (Via Conversa 8) — similar setting, slightly cheaper, the orecchiette with turnip greens (cime di rapa) here is excellent at €12. Both restaurants require booking for dinner. For lunch without booking: the bars near Piazza della Libertà serve panini with local mortadella and cured meats at €4–6.
Ostuni is 25km from Alberobello (the trulli capital, UNESCO World Heritage Site since 1996), 20km from Locorotondo (the white wine town — Locorotondo DOC white wine, made from Verdeca and Bianco d'Alessano grapes, is one of Puglia's best whites), and 35km from Fasano (where the Fasaneria safari park and the Egnazia archaeological site add a day trip dimension). The best day trip from Ostuni: drive the Valle d'Itria road through Martina Franca and Locorotondo to Alberobello (1.5 hours), visiting trulli, tasting Locorotondo white wine at a producer (Cantina del Locorotondo cooperative accepts walk-in visitors), and returning via the masseria road toward Cisternino for dinner.
Getting there: Ostuni station is on the Bari–Lecce line (trains every 1–2 hours from Bari, €8–12, 1.5 hours; from Lecce, €5–8, 40 minutes). The station is 3km from the old town — taxi €8 or bus every 30 minutes. By car: A14 motorway, exit Ostuni/Fasano.
When to go: May–June and September–October. July–August is tourist peak — the streets of the old town are packed and hotel prices double. The Ostuni beach resort (near the modern town, 8km from the old town) operates in summer only. The old town is accessible year-round and significantly more pleasant in shoulder season.
Where to stay: In the old town for atmosphere: Palazzo Pinto (Via S. Lorenzo 9, €90–150/night), a converted 18th-century palazzo with terrace views. In the surrounding countryside: masseria agriturismi with pools, olive groves, and cooking classes — typically €150–300/night including breakfast, 30% cheaper in spring/autumn.
Ostuni earned the name "La Città Bianca" (the White City) from its practice of lime-washing all exterior walls in white — a tradition maintained since the medieval period, originally for hygienic reasons (lime has antibacterial properties) and later preserved as a defining aesthetic of the town. The white lime (calce viva) is reapplied annually, which is why the whiteness is so consistent and bright. The contrast between the brilliant white walls, the blue Adriatic visible in the distance, and the dark grey-green of the ancient olive groves below the hill makes Ostuni one of the most visually striking towns in Italy. The white city designation predates modern tourism by centuries.
Ostuni's old town is 8km from its coastal resort area (Rosa Marina, Villanova, Pilone). The Adriatic beaches here are among the most pristine in Puglia — white sand, clear water, long stretches without development. In summer, a local bus connects the old town to the beach areas. Without a car, taxis to the beach cost €12–15. The best approach: rent a car for the day, combine beach morning with old town afternoon. The Ostuni area beaches are significantly less developed than the Salento beaches further south (Gallipoli, Otranto) and correspondingly less crowded in July–August.
Two days in Ostuni: Day 1 — morning old town walk (cathedral, rose window, belvedere views), lunch at La Cava, afternoon drive to the ancient olive grove zone south of Ostuni (some trees estimated at 2,000+ years — sign-posted from the SS379 coast road), aperitivo at sunset in Piazza della Libertà, dinner at Osteria del Tempo Perso (book ahead). Day 2 — morning drive to Alberobello for trulli (25km, 30 minutes), lunch in Martina Franca (wine bar on the main piazza, excellent Primitivo), afternoon at a masseria agriturismo for olive oil tasting, return to Ostuni for evening passeggiata. This covers the White City in depth and its immediate surroundings.
May–June and September–October are the best months for Ostuni. The weather is warm (20–28°C), the tourist crowds are manageable, hotel prices are 30–50% lower than August, and the local life of the old town is intact — restaurants serve locals, not just tourists. July–August is peak season: hot (35°C+), crowded, expensive. The Christmas period (December) is increasingly beautiful — the white walls decorated with lights and the annual presepe vivente (living nativity) in the old town. Ostuni in February–March is cold but empty and extraordinary to photograph.
Ostuni's central position in Puglia makes it an effective base for exploring the region without moving accommodation daily. Within 1 hour: Alberobello (trulli), Locorotondo (wine), Lecce (Baroque architecture — among the finest in Europe), Brindisi (ferry connections to Greece, Roman column marking the end of the Appian Way), Polignano a Mare (clifftop village, cave swimming). Within 2 hours: Matera (cave city, Basilicata region), Taranto (Magna Graecia museum), Otranto (the furthest east point of continental Italy). Related: Puglia wine tours, Puglia travel guide.
