Mola Castle was built during the Arabian period in the 9th century and enlarged in the 10th century by Almohad reign. It was restored by the Kingdom of Valencia in the 14th century. Today there are impressive ruins and the Gaudi-inspired church of Santuario Santa Magdalena.
The church was designed by an engineer from Novelda, José Sala Sala. The work was started in 1918, but was first completed in 1946. It is inspired by the famous La Familia Sagrada, Gaudi's masterpiece in Barcelona, but has several characteristics that make it unique.
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.
