The Torre de la Malmuerta is a gate tower in Córdoba. It was built in 1406–1408, by order of King Henry III of Castile, over a pre-existing Almohad structure, to defend the gates of Rincón and Colodro. Later it was also used as a prison for nobles.
Having an octagonal plan, the tower has an annexed arch.
The names, meaning 'Tower of the Wrongly Dead Woman', refers to a woman who, according to a legend, was killed here by her husband after a false accusation of adultery.
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.
