Bernalda Castle was probably built originally by the Normans in the 11th century and restored by the Aragonese during their domination, when it was enlarged, fortified and protected with a moat and a drawbridge. The current castle was built by Bernardino de Bernardo, secretary of King Alfonso II, around 1470.
Today Bernalda castle presents a quadrangular plan with angular towers, with a markedly late-fifteenth century mark, although it can be considered as the result of different architectural stratifications. The observation of one of the cylindrical towers, which is equipped with a high trunk-conical base, could in fact suggest an Angevin building intervention. In any case, the castle's closing walls seem to follow the nature of the terrain, and are mainly perpendicular. The continuous restorations must have reduced the width of the entire structure, which at the time of reconstruction could be configured with at least four other towers. Those residuals are however made up of a basement, used mostly as storage, followed by a ground floor with defensive preparations also oriented towards the inside of the enclosure, and two upper floors open on the courtyard, except for the tower of the southern summit .
The castle of Bernalda has fourteen wells, to draw water in case of siege.
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.
