Castillo de Alcaudete was built by the Arabs over the remains of a previous Roman fortification and taken by the Christians in 1085 during the reign of Alfonso VI. For almost three hundred years thereafter, the castle kept changing hands until 1340 when the Christians took it over.
The design is polygon in shape, adjusted to the terrain escarpments. The structure is surmounted by six towers, including the Tower of Homage, which has a door on the north side, guarded by two additional towers.
Today it has become a tourism-cultural space which houses the Interpretation Centre on the life of the Military Order of Calatrava. Visitors will go back to the 13th century to discover the construction of a castle on the border with the Nasrid Kingdom, the lifestyle and internal structure of the Order, the military armament used for the assault and defence of a fortress.
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.
