Castillo de Bujalance was built in the 10th century during the Caliphate of Abd-ar-Rahman III. It is a clear example of Muslim military architecture in Al-Andalus. It subsequently underwent several modernizations, most recently in 1512, which were paid for by Queen Joanna of Castile.
It is rectangular in shape, measuring 59 metres north-south and 51 metres east-west. The castle's original name, 'tower of the snake', and the fact that it had seven towers, led to the current name of the city and its coat of arms. In 1963, the Ministry of Culture declared the site a Bien de Interés Cultural monument. Currently, its courtyard is used as a cultural space, which is in the process of being cataloging, restored and reconstructed. Highlights include the Festival of Theatre, Music and Dance (Nights at the Citadel) and Andalusian Dinner during the summer months.
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.
