Church of Santa María a Real do Sar was built in the 12th century on the outskirts of the city. Interesting elements on the exterior are the small tower on the façade and the sturdy flying buttresses built between the 17th and 18th centuries. It has a basilical floor plan with three naves, separated by composite pillars decorated with plant motifs. It is covered with barrel vaults reinforced by rib arches. The sanctuary of the collegiate church has three apses; the central one is polygonal and the two side ones are semicircular. The interior lighting comes from the side openings and the rose window on the façade. Elements worth noting in the cloister include the decoration on the capitals, made by the workshop of Master Mateo.
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.
