The castle of Aymavilles is certainly the most characteristic and recognizable element of the Aymavilles for its position and architecture characterized by the four cylindrical towers crowned by 'murder holes' that enclose a central body with a square base.
The building, the origins of which date back to 12th century, was repeatedly reconfigured, changed its use from defensive to that of elegant lordly residence inside a great park.
The first record of the fiefdom and the castle date back to 1278, when it was simple a four-sided tower surrounded by a wall, according to the widespread type of the oldest Valdostan castles. Today, the large surrounding walls of the 13th century tower still exist, characterized by being strongly banked, along with a spinal wall divides it into sections at full height.
In 1357, Aimone de Challant became subject to fiefdom three years before the fiefdom of Aymavilles by Amedeo VI of Savoy, allowing it to operate as the defensive reinforcement of the facility, probably considered too vulnerable particularly the level approach on the surrounding land. The four corner towers were thus made: these have circular bases and are unequal in diameter, height and type of crenellations; 'murder holes' and arrow loops were also built, in addition to a double wall with a moat and draw bridge.
At the beginning of 18th century, the external fortifications were demolished and the land was arranged in terraces and gardens, changing the designated use of the building.
After many changes in ownership, the castle was purchased in 1970 by the Regional Administration, which has undertaken major restructuring in these past years.
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.
