The Château de l'Empéri is a 9th-century castle built on the rock of Puech which dominates the immense plain of Crau in the commune of Salon-de-Provence. The castle was the residence of the archbishops of Arles as well as the Holy Roman emperors. It is from the latter that the castle derives its name of the Empire which at this time included the East bank of the Rhône River. During 1481, at the time of the junction with Provence, it came under the power of kings of France. Arranged and embellished during the 15th and 16th centuries it was used as jails and barracks after the Révolution time. Hardly damaged by an earthquake in 1909, the buildings were restored by the Monuments Historiques during 1926 and hosted the museum of the old Salon, before hosting now the present museum of Art and History Military.
In the Empéri stayed several kings and queens of France. Francis I and his court, Louis XIV. In 1660 Catherine de' Medici came to consult Nostradamus, the famous astrologer would have predicted the throne for her three sons and the accession of her nephew, the future king Henri IV.
The castle contains faithful representations of the various army corps from the Napoleonic Wars to the present day in its museum. The museum also contains a copy of a bed belonging to Napoleon I at Saint Helena.
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.
