Monastery of San Miguel de Las Dueñas founded in the 10th century and renovated in the late 12th century under the Cistercian rule. Its original name was San Miguel de Almázcara. A Romanesque portal gives way to the chapterhouse.
The 17th century church houses a Baroque altarpiece and the renowned reliquary of the choir. There are two cloisters, the Claustro del Palacio (17th century) and a Neoclassical one.
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.
