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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
