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:
Royal Palace of Naples was one of the four residences near Naples used by the Bourbon Kings during their rule of the Kingdom of the Two Sicilies (1734-1860): the others were the palaces of Caserta, Capodimonte overlooking Naples, and the third Portici, on the slopes of Vesuvius.
Construction on the present building was begun in the 17th century by the architect Domenico Fontana. Intended to house the King Philip III of Spain on a visit never fulfilled to this part of his kingdom, instead it initially housed the Viceroy Fernando Ruiz de Castro, count of Lemos. By 1616, the facade had been completed, and by 1620, the interior was frescoed by Battistello Caracciolo, Giovanni Balducci, and Belisario Corenzio. The decoration of the Royal Chapel of Assumption was not completed until 1644 by Antonio Picchiatti.
In 1734, with the arrival of Charles III of Spain to Naples, the palace became the royal residence of the Bourbons. On the occasion of his marriage to Maria Amalia of Saxony in 1738, Francesco De Mura and Domenico Antonio Vaccaro helped remodel the interior. Further modernization took place under Ferdinand I of the Two Sicilies. In 1768, on the occasion of his marriage to Maria Carolina of Austria, under the direction of Ferdinando Fuga, the great hall was rebuilt and the court theater added. During the second half of the 18th century, a 'new wing' was added, which in 1927 became the Vittorio Emanuele III National Library. By the 18th century, the royal residence was moved to Reggia of Caserta, as that inland town was more defensible from naval assault, as well as more distant from the often-rebellious populace of Naples.
During the Napoleonic occupation the palace was enriched by Joachim Murat and his wife, Caroline Bonaparte, with Neoclassic decorations and furnishings. However, a fire in 1837 damaged many rooms, and required restoration from 1838 to 1858 under the direction of Gaetano Genovese. Further additions of a Party Wing and a Belvedere were made in this period. At the corner of the palace with San Carlo Theatre, a new facade was created that obscured the viceroyal palace of Pedro de Toledo.
In 1922, it was decided to transfer here the contents of the National Library. The transfer of library collections was made by 1925.
The library suffered from bombing during World War II and the subsequent military occupation of the building caused serious damage. Today, the palace and adjacent grounds house the famous Teatro San Carlo, the smaller Teatrino di Corte (recently restored), the Biblioteca Nazionale Vittorio Emanuele III, a museum, and offices, including those of the regional tourist board.
