Hrubý Rohozec is a castle in Turnov. The original structure was connected to a polygonal tower by a defensive wall. Its purpose, in the 14th century, was to monitor the trade route running below it. Between the two parts of the castle Jan von Šelmberk, and later Konrad Kraiger Kraigk, built Gothic palaces. During the Renaissance the Wartenberg family rebuilt the complex in the style of a chateaux.
Albrecht von Wallenstein bought it in 1621 followed by the noble family Desfours, who held it until 1945. After 1822 the castle was upgraded on the basis of plans by the architect Jan F. Joendl. The castle's library, dining room, bedroom and a blue room are open to the public and display their original furnishings.
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.
