Canena Castle is a Renaissance building from the 16th century, designed by the Spanish Renaissance architect Andrés de Vandelvira (1509-c. 1575). It belonged to Francisco de los Cobos, private secretary to Charles I and a great patron of the Renaissance in Úbeda and the surrounding area.
The building we see today dates from the 17th century. It adopts an almost square ground plan delimited by two large towers at the ends of the main façade and two smaller and apparently incomplete towers on the rear façade, all them circular. One of the most imposing features is the square keep, which used to be surrounded by a moat, now filled in, and accessed by a drawbridge.
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.
