The Cathedral of Milan, known as the Duomo di Milano, is one of Italy's most famous landmarks and an important centre of religious pilgrimage. Located in the centre of Milan, the Cathedral is an impressive example of late-Gothic architecture and is considered one of Italy's most beautiful churches. The Cathedral was started in 1386 and took nearly 600 years to complete, making it the most prominent Catholic Cathedral in Italy and the fifth-largest Cathedral in the world. It is a stunning example of Gothic architecture with its five naves, 135 spires, and thousands of statues adorning its exterior. Visitors can explore the Cathedral's vast interior and admire its painted frescoes, stained glass windows, and exquisite marble altars.
