The Basilica di San Giovanni e Paolo is one of the largest churches in Venice with the status of minor basilica. After the 15th century the funeral services of all of Venice's doges were held here, and twenty-five doges are buried in the church.
The huge brick edifice was designed in the Italian Gothic style, and completed in the 1430s. It is the principal Dominican church of Venice, and as such was built to hold large congregations. It is dedicated to John and Paul, not the Biblical Apostles of the same names, but two obscure martyrs of the Early Christian church in Rome, whose names were recorded in the 4th century but whose legend is of a later date.
In 1246, Doge Jacopo Tiepolo donated some swampland to the Dominicans after dreaming of a flock of white doves flying over it. The first church was demolished in 1333, when the current church was begun. It was not completed until 1430.
The vast interior contains many funerary monuments and paintings, as well as the Madonna della Pace, a miraculous Byzantine statue situated in its own chapel in the south aisle, and a foot of Saint Catherine of Siena, the church's chief relic.
The Renaissance Equestrian Statue of Bartolomeo Colleoni (1483), by Andrea del Verrocchio, is located next to the church.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
