Acaya Castle wa built by the Knight Alfonso of Acaya in around 1506. In the following years, his son Gian Giacomo dell'Acaya, a famous architect, rebuilt the entire complex, transforming it into a fortified hamlet and making it the main centre of his estate. He also renamed it Acaya. After his death in 1570, the hamlet was sold and Acaya began to decline slowly, until its rebirth in the 20th century.
The Castle, which has a trapezoidal base, is accessible through a single bridge. The fortified walls are reinforced by two cylindrical towers. A stairway leads up to the rooms on the upper floor, including the bastion hall, with its painting of the Spanish Kings' coats of arms, and a room decorated with classically-styled motifs carved in Lecce stone.
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.
