The first manor house was made out of wood and the new palace was built in 1800-1804 in the late classical style, designed according to the project by the German architect J. G. Berlitz. There is stone bridge, leading to the palace. On the other side of the river there are remnants of the manor buildings; house of the servants, stables, house of the steward and barns. The palace was burned down by local peasants during the Revolution of 1905. However, German baron von Manteuffel renovated it by the project of Paul Schultze-Naumburg in 1907. The renovation of the Kazdanga palace became an important event for the development of the Neo-Classicism style. It was designed by the well known German architect and Neo-Classicism Paul Schultze-Naumburg. In contrast to scenic, borrowed forms, the architect declared a return to the Homeland tradition and accuracy.
The reconstruction of the Kazdanga palace demonstrated a new approach by the architect to the original image of the building. It is noteworthy that the palace, designed in about 1800, was one of the most splendid monuments of Classicism architecture in Courland. Its restoration served as a starting point for re-evaluating both patterns of pure Classicism and local building traditions. Even elements of scientific restoration could be observed in the course of reconstruction. The principle of historical verity was important in designing the interiors and replicas of the furniture that had been destroyed.
During the First World War the palace was again devastated. It was rebuilt between 1925-1927. In 1930 the Kazdanga Agricultural Trade School was housed in the palace. The school is still situated there. Near to the palace is a house of chevaliers. It has well preserved interior, like baroque style stairs and ornamented parquet floor.
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.
