According to the legends, Al-Mansur (legendary Moorish leader) was defeated near Calatañazor Castle in a bloody battle against Christian troops in 1002. The fortress originally had two quadrangular towers on the corners and a keep. Later on, circular towers were added to the southern wall and semi-circular ones next to the main entrance. The current appearance dates mainly from the 14th century.
The castle is part of the walled village of Calatañazor but separated from it by a dry moat that was cut out of the rock. On the castle's irregular enclosure there are ruins of several towers and the keep, which is situated next to the entrance over the moat.
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.
