The Château de Castelnau-de-Lévis was built at the beginning of the 13th century by Gicard Alamon, and called Castelnau de Bonnafonds. It was rebuilt by the Lévis in the 15th century, when the seigneurie came into the possession of Hugues d' Amboise, baron d'Aubijoux; the fief remained with his descendants until the seventeenth century. Hugues' grandson, Louis d'Amboise, comte d'Aubijoux and baron de Castelnau-de Bonnafous, restored the castle and dwelt in it. The narrow square watchtower (tour de guet) is 40m tall.
Apart from the watchtower, all that remains today are remnants of other buildings. From the castle, there is a good view of Albi and the Tarn valley.
The castle is privately owned.
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.
