The The Chateau at Klášterec nad Ohří is a prominent landmark in the town's recently restored historic urban conservation area. The chateau is set in an extensive landscape park, with 220 tree species, some rare from around the world. The park features a Baroque style sala terrena pavilion, with a gloriette mezzanine decorated with architectural sculptures by Jan Brokoff (1680s).
The park's northern section has an installation of the Stations of the Cross (1690s) and the Church of the Holy Trinity with the Crypt of the Thun Noble Family.
The Chateau at Klášterec nad Ohří exhibits an extensive porcelain collection from the Museum of Decorative Arts in Prague. Occupying 21 rooms on the chateau’s first floor, the collection of Bohemian and Czech porcelain documents the more than 200-year-old history of porcelain manufacturing in Bohemia. The historical showcases and interiors feature the output of porcelain factories in Slavkov, Klášterec nad Ohří, Březová, Kisibl, Chodov, Stará Role, Dalovice, Prague, Loket, Budov and Ždanov.
The display presents a selection of early porcelain produced in China and Japan, as well as Meissen, Vienna and Nymphenburg between the 17th and 19th centuries.
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.
