Ostuni is WHITE. Every building, every wall, every stairway is painted with calce (lime wash) — a tradition that began in the Middle Ages (lime is antibacterial, it reflects the sun, and in plague times it was mandatory). The result: a hilltop city that GLOWS. From a distance, Ostuni looks like a pile of sugar cubes stacked on a green hill. At the summit: the Cattedrale (15th century, Gothic-Romanesque, a rose window with 24 radiating columns). Below: a cascade of white alleys, arches, staircases, courtyards — the old town is a LABYRINTH built for getting lost. Around the hill: the olive groves of the Valle d'Itria — some trees are 1,000+ years old, their trunks twisted into sculptures by centuries of growth. The Adriatic coast is 8km east — white sand beaches below a white city.
The centro storico (old town): Enter through Porta Nova or Porta San Demetrio. Climb. The alleys narrow. The white walls close in. Arches bridge the streets overhead. Every turn reveals a different composition of white, shadow, and sky. Cattedrale dell'Assunta (Piazza Beato Giovanni Paolo II): The facade — a 24-column rose window, a Christ figure above, golden limestone against the white of the surrounding houses. Inside: surprisingly restrained after the Baroque excess of Lecce. Museo di Civiltà Preclassiche della Murgia Meridionale (€5): The star exhibit: Delia, a 25,000-year-old pregnant woman found in a cave near Ostuni — the oldest evidence of a full-term pregnancy in a burial. Piazza della Libertà: The main square at the base of the old town — the Sant'Oronzo column (1771), the morning market, the aperitivo terraces with the view of the old town rising above.
The olive groves: Ostuni sits in the LARGEST olive-producing area in Italy. The monumental olives (ulivi monumentali) — trees with trunks 5-8m in circumference, 1,000-3,000 years old. Some were saplings when the Romans ruled. Visit Masseria Il Frantoio (SP14, 5km south — working olive farm, tours of the ancient grove, tasting, €15-25).
From Bari: Train 1h (Trenitalia, €7-10). From Brindisi: 25 min. From Alberobello: 30 min. The coast: Ostuni Marina (8km east) — Pilone, Costa Merlata, Rosa Marina — white sand, dunes, clear Adriatic. Stay 3 nights: Masseria experience (converted fortified farmhouses, €80-200/night — Masseria Cervarolo, Masseria Salinola). Eat: Orecchiette con cime di rapa (the Puglia dish). Bombette (stuffed meat rolls, the street food of the Valle d'Itria). Frisella con pomodoro (the bread salad that started as poor food and became a delicacy). Puglia →
