An exceptionally large and elaborate Gothic cathedral on the main square of Milan, the Duomo di Milano is one of the most famous buildings in Europe. It is the largest Gothic cathedral and the second largest Catholic cathedral in the world.The Duomo of Milan blurs the distinction between Gothic and neo-Gothic, for the Gothic west front was begun in 1616 and completed 200 years later. Only in its details does it reveal its Baroque and Neo-Classical date. From 1900 some of the less Gothic details of the facade were replaced in a true Gothic style, to designs of Giuseppe Brentano.
