At the beginning of the 14th century, the noble family of Vartemberk ordered the building of a castle on the hill near Nová Paka. It was originally called Goldenberk or Kolmburk, today`s Kumburk.
Because of massive renovation work, we do not know much about the original look of the castle. At the northeastern side, there are remnants of probably a walled fortification that may have been developed along the whole core structure. The fortification to protect against cannon attack is one of the best examples of the efforts made in the mid 15th century to protect places in an active way. From 1621 Kumburk was in the possession of Albrecht of Valdštejn. After his death, the castle changed hands several times and then, after 1658, Kumburk was nearly destroyed. In spite of that, nowadays it belongs among our most interesting castles.
The shortest way is from the railway station in Syřenov, along the yellow trail (3km). Other alternatives are Nová Paka and Stará Paka (4km) or the popular red tourist trail from Ploužnice (7km).
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.
