The Arab Baths of Jaén (Baños Arabes de Jaén) are a well-preserved historic hammam (Islamic bathhouse). The bathhouse dates from the 11th century during the Taifa or late Caliphal period, but may have undergone later alterations, probably in the 12th century. It is one of the largest known examples of Andalusi bathhouses, and is distinguished from others by its particularly large 'warm room' (bayt al-wasti).
Following the Christian conquest of the city by Ferdinand III in 1246, the baths remained in use for a while until they were repurposed as tanneries. In the 16th century Don Fernando de Torres y Portugal (Count of Villardompardo and Viceroy of Peru) built himself a private palace on top of the baths, thus hiding them for centuries. They were only definitively rediscovered by Enrique Romero de Torres in 1913 during a survey of historic buildings in the city. Archeological studies later followed and the site was declared a Cultural Heritage Property of Spain in 1931. Today it is open to visitors as a historical attraction as part of the Palacio de Villardompardo.
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.
