It lies in the historic centre of Ostuni, the beautiful 15th century Cathedral, dedicated to Santa Maria dell’Assunzione, a national monument since 1902, which stands on top of the highest hill in the white city.
Renovated in the late fifteenth century, after a strong earthquake, the Cathedral has a majestic facade with three portals, surmounted by three rose windows, including the central one, a triumph of medieval symbolism, with 24 rays formed by columns and arches and in the center the figure of Christ, surrounded by the apostles and seven heads of cherubs, holding the earth as a sign of protection.
In the shape of a Latin cross, the interior of the church is divided into three naves separated by arches of 5 columns. The central nave has three beautiful 18th century paintings, with scenes from the life of Jesus, set in the ceiling, and fascinating paintings dedicated to the patron saint Saint Oronzo and the martyrdom of Saint Blaise.
