The Former Cathedral of Baeza was the cathedral episcopal see of the Roman Catholic Diocese of Baeza, which has a Visigothic period, was suppressed after some time under Moorish rule and was shortly restored after the Reconquista under the Kingdom of Castile in the thirteenth century, but suppressed for good, never again to regain (co-)cathedral status.
The site, like the land, alternated between mosque and church during 12th and 13th centuries. The apse still maintains Gothic tracery, but in the 16th-century a major reconstruction by Andrés de Vandelvira in Renaissance-style created the present church. The construction of the cathedral finally ended in 1593, shortly after the death of Andrés de Vandelvira.
The church forms part of a UNESCO World Heritage Site with other monuments in Baeza and in the nearby city of Úbeda.
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.
