Miranda del Castañar Castle, or at least the tower of homage, was probably built by Pedro de Zúñiga. By means of a small enclosure that serves as a gate, the tower is attached to another D-shaped tower and other remains that might belong to a previous fortress. The round loopholes are the usual 15th-century artillery loopholes.
Miranda was founded around 1215.The well preserved wall probably dates from that time. Prior to the death of Diego de Zúñiga, the fortress is taken by García Alvarez de Toledo, the Duke of Alba, who claimed to be entitled to have it.
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.
