Apulia is the heel of Italy’s boot: and one of its most visually arresting regions. The conical trulli of Alberobello and the Valle d’Itria rise from a landscape of ancient olive groves, some of them thousands of years old. White-washed hill towns: Ostuni, Locorotondo, Cisternino: glow against the flat countryside. The Salento coast stretches south to Santa Maria di Leuca, where the Adriatic and Ionian seas meet, and Lecce offers some of the most extravagant baroque architecture in Europe.
