Linköping Castle is Sweden's oldest profane building. The oldest part, west wing, dates from the 12th century. Currently the residence of the County Governor of Östergötland, the castle has been home to governors and bishops since the 13th century. The most famous bishop to live in castle was probably Hans Brask, Sweden's last Catholic bishop.
The Linköping Bloodbath, the public execution by beheading of five Swedish nobles in the aftermath of the Battle of Stångebro, in 1600 was held in either in Linköping market square or in the castle courtyard.
In 1700 most of Linköping city burned down, but the cathedral and castle survived. The decayed castle was moved as a city prison. The restoration began In 1796 and then the castle got its classicism style appearance. In 1880 it was again renovated to the neo-Renaissance style, but restored back to the current classicism in 1930s.
The old tower of the museum features an exhibit of the history of the castle, cathedral and diocese from the 12th century to today. Unique 14th century textiles and other valuables - especially from Sweden's empire period - are on display in the treasury. You can see a big model of the castle's state apartments in the great hall.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.
