The Château de Calmont d'Olt is perched atop a basalt dyke. It provides a panoramic view of the Aubrac highlands.
Flint fragments and a polished stone axe are evidence of occupation of the site for 5,000 years. The ministerium Calvomantese was first mentioned in 883, in documents from the Abbey at Conques. It has always had a military significance, commanding the road from Rodez to Aubrac and, more widely, the crossing of the River Lot on the Toulouse-Lyon route. The building of the castle was begun in the 11th century built and continued until the Hundred Years' War with the building of a second curtain with eight towers in 1400. Beyond this date, there was no further development. Abandoned by its owners in the 16th century, the castle fell to ruin. The castle, in its present state, is an important milestone in the history of castle building in medieval Rouergue. It bears witness to the architectural adaptations of castles to the technical progress of the Hundred Years' War.
The castle is part of the Route des Seigneurs du Rouergue (Route of the Lords of Rouergue) which groups 23 castles.
The site highlights the theme of siege warfare. Full-scale war machines have been reconstructed and visitors may assist in the launching of projectiles with. There is a siege tower from the 15th century with bombards, trébuchets from the 14th century and pierrière from the siege of Toulouse from the 13th century. Visitors are also invited to take part in other demonstrations including archery, fencing and making chain mail.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
