Highlights: St. John's Cathedral in Valletta is one of the more famous cathedrals in the world. It was built by the Knights of Malta from 1573 to 1578. It is the place where leaders and knights hold major religious ceremonies and sacrifices. The church is in early Baroque architectural style, partly imitating Gothic. Although the exterior is pure white and plain, the interior ornate decoration is breathtaking. The entire dome of the church is a large fresco, painted by the Italian painter Madia Brady, showing the life story of St. John, and the carved stone walls can make people understand the history of the Knights. This church is also known as one of the more beautiful churches in Europe. The interior of the cathedral is further divided into eight chapels, dedicated to the patron saints of the eight parts of the Knights. There is also a Cathedral Museum (CathedralMuseum), one of the more famous works of art is Caravaggio's "Saint John beheaded".
