Italy is home to many of the world's largest, oldest and opulent churches. Clockwise from left: Florence Cathedral, which has the largest brick dome in the world;^[1]^[2] Pisa Cathedral, a notable example of Romanesque architecture, in particular the style known as Pisan Romanesque;^[3] Milan Cathedral, the largest Italian church and the third largest in the world; and St Mark's Basilica, one of the best known examples of Italo-Byzantine architecture.^[4]

Religion in Italy has been historically characterised by the dominance of the Catholic Church, the largest branch of Christianity, since the East–West Schism.^[5]^[6] However, due to immigration, notably the influx of Muslims, Orthodox Christians, Protestants, Buddhists and Hindus, as well as proselytism and secularization, have increased religious pluralism in the 21st century. Italy also features a pre-Christian Jewish community and one of the largest shares of Jehovah's Witnesses in the world.
