Cly is a castle in Saint-Denis, overlooking the Dora Baltea river, belongs to the so-called primitive style of castle, consisting of a keep with a surrounding wall. The ruins rise from a bed of metamorphic rock, on the edge of a fault line which extends to the Castle of Quart.
Cly was first mentioned in a document from 1207, in which the 'chapel sancti Mauricij de castro Cliuo' is mentioned among the goods of the Vicarage of Saint-Gilles in Verrès, but the keep has been dated to 1027 using an analysis of the tree rings in its timbers (dendrochronology). Originally a fief held from the Counts of Savoy, in 1376 the direct ownership passed to the Duchy of Savoy, which installed a castellanto administer it for them until abandoned in 1550. The castle fell to ruins in the centuries that followed.
Eventually the castle ruins became the property of the nearby town of Saint-Denis. The castle is visible atop the hill overlooking the town of Chambave. The castle is open to guided tours only in July and August.
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.
