Saint Germain castle in Montjovet played an important part in the history of Val d’Aosta. Few traces remain of its original structure and its construction date is not known for certain. At the end of the 13th century, the Savoy became the owners, replacing the Montjovet family. As already happened in Bard, in this case too, the pretext was provided by the abuse of power that Feidino Montjovet acted on villagers and wayfarers. The castle was later sold to the Challant family but returned to the Savoy in 1438, when Amadeus VII installed a garrison there, which remained active until 1661, when it was transferred to the fortress in Bard, leaving Montjovet castle open to decay.
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.
