About 1300, a knight named Conrad von Tronecken is mentioned in document for the first time, and then somewhat later the Feste Troneck (fortification), which, however, is probably much older. Having been destroyed several times, by Cologne, Imperial and French troops, and then finally by an earthquake, only remnants of Dhronecken castle are left now, although a corner tower can still be climbed.
On the old castle's foundations in modern times, commercial buildings were built, and also a bigger, tall building – called the Schloss – which is today used as a forester's office. Also, a barn with beam construction serves as a community centre for the municipality of Dhronecken. The attractively laid-out castle gardens have been continuously planted and tended since 1985.
Below the castle is found a nature play area on both sides of a brook. A ford with stepping stones, a forumlike playing and gathering place on a slope, made out of mighty stone blocks, wooden footbridges over wetlands left in their natural state, playing houses, a suspension bridge and a monorail are the great attractions not only for children, but also for adults.
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.
