Santa María Jus del Castillo Church was built in the 12th century on the site of a synagogue, since this was then the Jewish quarter of the city. Its original name was Iglesia de Santa María y de Todos los Santos. It was used as a church until the 17th century. Today it is used as an Interpretation Center of the Romanesque and the Camino de Santiago. It was declared a Site of Cultural Interest.
It is a church with a single nave. The apse and the central body of the church are Romanesque, but the façade and tower are from the Baroque period.
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.
