San Giuseppe church was erected in 1756-1796 under the patronage of the Benedictine order. The church and an adjacent convent of nuns occupied a site where prior to the 1693 earthquake had been located the church of San Tommaso. The architect is unknown, but in the circle of Rosario Gagliardi. Like many local churches, the façade has three highly sculpted order, decorated with statues of Saints of the Benedictine orders, including Saints Benedict and Mauro above and St Gertrude and Scolastica below. Near the entrance are statues of St Gregory the Great and St Augustine by Giambattista Muccio in 1775. The entrance portals have iron grillwork screens (1774) by Filippo Scattarelli.
The interior has an oval layout, but kept a large choir and coretti situated over the entrance and flanking the nave, where the nuns could hear the mass while remaining cloistered. Over the vault is a fresco depicting the Glory of St Benedict with St Joseph (1793) by Sebastiano Monaco. The walls are elaborately stuccoed (1793) by Agrippino Maggiore and the Cultrera di Licodia Eubea. The altars (19th century) have elaborate scagliola, and have altarpieces by Tommaso Pollace and Giuseppe Crestadoro, depicting the Trinity, St Mauro, St Benedict, and Ste Gertrude. The pavement has white stone and maiolica tiles. The Vestibule has statues depicting St Benedict (17th century) and a silver-coated St Joseph (1785).
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.
