St. Paul's Cathedral, also known as the Metropolitan Cathedral, is the world's fourth-largest Gothic cathedral and the gateway to the tourism of São Paulo. It was built in 1913 and the construction lasted for 40 years, becoming a luxurious project in São Paulo's 400th anniversary. In terms of artistic features, it blends Gothic and Renaissance styles. In addition to the Gothic spires, the Cathedral's semi-circular arch vouchers and the Center are in the Renaissance style. The designer imitates Florence's Cathedral of Santa Maria del Fiore.
