The Château de Budos is largely the work of Raymond Guilhem de Budos, nephew of Pope Clement V. Originally built by his uncle, he remodelled it from 1306, the old family castle taking on the architectural layout of the neighbouring castle, the Château de Villandraut.
In 1422-23, the English king Henry VI took possession of the castle and put it in the charge of Pons, lord of Castillon. Around 1433, Henry conceded the lands and castle to his son, the Duke of Gloucester. In 1446-47, Budos was given to the Count of Foix, following the death of Gloucester. After the conquest of Guyenne (Aquitaine), the Budos family, having supported the cause of the French crown, regained possession of its seigneuries in Guyenne. In 1652, the cavalry captain Lasserre seized Budos which he sacked and pillaged and burnt the archives. The seigneury of Budos stayed in the family of La Roque until the French Revolution. In 1825, the castle was sold as national property. In 1851, the Gironde Commission of Historic Monuments was informed of the castle. They learned at the same time that stones originating from the castle had been sold to a builder by the state.
The castle is rectangular in plan. A vast U-shaped building range around the courtyard is protected by a high wall contained by towers at the corners. Entry is made through a high square tower. On each face, a non-projecting square tower dominates the curtain wall and the buildings. The north-east curtain wall seems to have been raised several times. The crenellations of the first roundwalk have been filled in.
The ground level appears flat today thanks to embankments which have been placed there. Originally, the ground sloped and the architecture provides evidence of the different levels.
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.
