The palazzo del Capitaniato was designed by Andrea Palladio in 1565 and built between 1571 and 1572. The palazzo is currently used by the town council. It was decorated by Lorenzo Rubini and, in the interior, with frescoes by Giovanni Antonio Fasolo. Since 1994 the palace has been part of the UNESCO World Heritage Site of the 'City of Vicenza and the Palladian Villas of the Veneto'.
The Palladian loggia replaced an analogous building which had stood on the same site from the Middle Ages, and which had already been reconstructed at least twice during the Cinquecento: a covered public loggia on the ground floor and an audience hall on the upper storey. The new construction became economically viable in April 1571 and works began immediately. Palladio supplied the last drawings for the moulding templates in March 1572 and by the end of that year the building would have been roofed, since Giannantonio Fasolo could paint the lacunars of the audience hall while Lorenzo Rubini could execute the stuccoes and statues.
While the upper hall displays a flat, coffered ceiling, the ground-floor loggia has a sophisticated vault covering, certainly to better sustain the weight of the hall. The overall design is extremely sophisticated, as witnessed for example by the portals which open within the niches and follow their curvature.
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.
