Luna castle dates from the 13th century and was built under control of 'Guzmán the Good' upon a fortified convent of ribat or Muslim origin, in the 11th century. It is rectangular with five crenelated towers, and its interior is structured around a central courtyard.
Property of the Dukes of Arcos, the Ponce de León used the castle as a residence and there is evidence that the Catholic Monarchs visited the city and stayed there.
The Luna Castle is a symbol in itself for citizens of Rota, Cadiz, and proof of this is its presence on the coat of arms of the village. It has housed a hospital and a school, and is currently the location of the City Hall of Rota.
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.
