Fuensaldaña Castle construction started in the 13th century, but it is not until the 15th century that the structure acquires today's configuration. It was built by the Vivero family. The family became linked to the region's history when the future Catholic Monarchs got married in their castle.
Inside, the building was shaped as a 'U' around the cortyard, which today has been made into the parliament floor. During the Comunidades war, it was peacefully occupied by the comunero troops. The castle was the General Assembly of Castilla y León.
Inside the keep are four vaulted halls out of ashlar masonry. The keep, like the curtain walls, is also equipped with round towers at its corners, two nice turrets and battlements.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
