The Gothic Roupov castle was founded in the 13th century, and after a Renaissance modernization was one of the most beautiful Czech castles. The now completely standing part was built later and is being used by the current owners, the old ruined part hides many original architectural pieces, and is freely accesible. The original black kitchen with a medieval chimney is still present, and a gothique well. The castle was in usable state in the late 18th century, but slowly deteriorated, and the old part was disassembled for stone when a nearby village burned down and building material was needed. Some walls collapsed in 1817 and the castle became a ruin. Today the old part is conserved.
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.
