The Château de Beaucaire is a ruined castle in the commune of Beaucaire. Existing structures date from the 12th and 16th centuries, with other elements from various times in the Middle Ages.
First built in the 11th century, the castle was torn down on Richelieu's orders. It used to be protected by a wall, the trace of which can still be followed. It includes a strange polygonal tower perched on a rocky spur, the façades dominating the sheer drop, and a fine round corner tower. Once inside the walls, a staircase leads to a small Romanesque chapel with a charming, sculpted tympanum, and then to the musée Auguste Jacquet. The museum has exhibits on the region's archaeology (dating back more than 40,000 years) and popular arts and traditions.
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.
