Château de Hierges is a partially ruined castle. The castle, originally called Château de Jerusalem (Castle of Jerusalem) was built on the site of a castrum whose origins date back to the 9th century, when the seigneurie of Hierges was part of the property of the house of Ardenne. At the time of the Crusades, the fortress of Hierges was given to the Prince-Bishopric of Liège and, in the 12th century, the castle was destroyed.
The castle was rebuilt in the 16th century, starting in 1560, with more comfort and openings for firearms. In the 18th century the former common and the dovecote were added. The castle was assaulted by revolutionaries in 1792 and destroyed by fire on 18 November 1793.
Of this Meuse-style Renaissance castle, there remain the curtain walls and three large round partially ruined towers, constructed in red brick and blue stone. The fourth covered tower, semi-circular in blue stone from Givet, is inhabited by the current owner.
On the towers, gun emplacements provided for mutual defence by cross fire. Some windows have cross mullions.
The exterior gardens have been restored to present the appearance they would have had during the Renaissance.
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.
