San Giorgio in Braida church was built in the 16th century in the medieval quarter of Veronetta. The 12th-century bell tower is what remains of a monastery built in the 11th century. The facade is marble white with two rows of pillars. The statues of St. George and St. Lorenzo Giustiniani are on sides. The interior has a single nave built between 1536 and 1543, and contains key works of art. Above the main door is a Tintoretto painting depicting the baptism of Christ. The church houses Paolo Veronese's masterpiece, The Martyrdom of St. George. In 1540 Michele Sanmicheli built the dome of the church. In 1776 were cast the six bells tuned in the scale of G major, on which was developed the Veronese bellringing art.
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.
