Standing on a marked, rocky promontory, Ussel castle overlooks the south side of the residential area of Châtillon. Built by Ebalo II of Challant in the mid-14th century, the castle marks a change in Valdostan fortress architecture. Indeed, it is the first single body castle in Val d’Aosta, which was the last evolutionary phase of medieval castles, and marked the passage between the contemporary castle in Fénis and the rigid forms in Verrès. Having passed on numerous occasions from the Challants to the Savoys and vice versa, the castle then became a prison, until it was abandoned completely. Having bought the castle from the Passerin d’Entrèves family, heirs to the Challants, in 1983 Baron Marcel Bich donated it to the regional authority, which restored it and earmarked it as an exhibition centre.
With a large, rectangular layout, the castle is an example of good masonry that culminates in blind arcades, not present on the north side, and beautiful mullioned windows each different from the next, with floral and geometric decorations. The corners on the south side (facing the mountain) have two round towers, which were originally connected via a walkway, protected by battlements. The south side also has an entrance with an overhead machicolation. The north side, which faces Châtillon, has two four-sided towers, with a slightly projecting watchtower in between, a symbolic element of feudal power.
The monumental fireplaces remain, with large shelves placed on the same ascending line, exploiting a single flue, and traces of the stairs and floor divisions.Before restoration work began, the manor was mostly in ruins; however a precise archaeological assessment enabled identification and reintegration of the missing parts. A picturesque walkway was added along the battlement, where visitors can admire the Châtillon plain and its historic buildings.
The castle host exhibitions and it’s open only when exhibitions take place in it.
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.
