Liebenstein Castle was probably built in the 13th century as well as near Sterrenberg castle. Both were owned by feodal lords of Bolanden (later Sponheim-Dannenfels). The gate tower was added 1363 and tower in 1380 and the castle was enlarged in the 15th century. However, already in 1529 it was abandoned and left to decay. The major restoration took place in 1977 and today Liebenstein is a hotel and restaurant.
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.
