Inspired by French palace architecture of the 17th century, graceful, porticoed Palazzo Ducezio is one of architect Vincenzo Sinatra's finest works. The lower level, dating from the mid-18th-century, houses the jewel-box Sala degli Specchi (Hall of Mirrors), a richly stuccoed, Louis XV-style room once used as a small theatre. The top floor, built in the mid-20th-century, offers a panoramic terrace with level views of Noto's cathedral.
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.
