Montquintin Castle was probably originally designed to defend the southern border of the counts of Chiny. It was built in the 11th century by order of Louis II, Count of Chiny (born 1025). Over the centuries the castle has undergone many changes. The central part was rebuilt the 18th centuryt by the Bishop of Hontheim, last owner. In 1869 a fire destroyed the castle. The basement includes a vaulted cellar, which is very well preserved.
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.
