Originally the Ducal Palace of Lerma had immense gardens below it, on the banks of the river, with fountains, stately homes and seven chapels, of which one (Cristo) remains. All documents relating to its construction have been conserved. A 17th-century work, building started in 1601 under commission from Francisco Gómez de Sandoval y Rojas, Duke of Lerma. Its architect was Francisco de Mora and is it is considered de Mora's masterwork and one of the finest buildings of that era.
During the Spanish Civil War the building was used as a prison. It is currently used as a parador.
The doorway is crowned by a frontispiece held up by columns. The large walnut door is decorated with 520 bronze nails. Above the door are two of the duke's coat-of-arms, decorated with laurel. The railings of the windows and balconies are painted blue and gold.
The interior of the patio round arches on each side. The columns are made of single pieces of granite (the quarries were owned by the duke). On the upper level the columns do not support arches, but rather a running frieze with iron balconies between them, and windows which were originally made from walnut wood.
The palace has four towers at the corners, whose spires were also recovered after the restoration works. No palace could have more than two towers except those belonging to kings, but the Duke of Lerma was given this privilege due to his great powers in Court.
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.
