Vipava Castle was built by the Patriarchate of Aquileia and first recorded in 1275 as Castrum Wipaci superioris. It was the residence of the knights of Vipava until the mid-14th century, when it became a ducal fief, granted to a long series of noble and knightly families, including the knights of Rihemberk, lords of Snežnik and Belopeš, Counts of Celje, barons Herberstein, Counts Thurn, the noble family of Edling, counts Thrillegkh, and finally the counts Lanthieri, who abandoned the decaying castle in the 17th century.
The ruins of the Romanesque structure trace the rectangular layout of its thick walls, enclosing two residential buildings guarded by an impressive defensive tower.
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.
