Situated on a hill overlooking the valley of Thiele, the Champvent castle of is on of the best preserved medieval castles in Vaud canton. It was probably built around 1250 by Henri de Grandson. His family occupied the castle until 1336. The castle and the lordship then passed in Burgundy until 1476 when it was burned after the Battle of Grandson (in Burgundian Wars). Champvent castle was rebuilt after 1536 and became a private property.
The construction plan derives its origin from Byzantine architecture and undoubtedly became to the Western Europe at the time of the crusades. Today castle is a rectangular building flanked by round towers.
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.
