Slushko Palace was erected in 1690–1700 by voivode of Polock Dominik Słuszko of the Clan of Ostoja, who ordered creating an artificial peninsula on Neris for the purpose of building the palace there. The peninsula was formed from the soil of the leveled down hill separating Antakalnis from the Vilnius Castles. Initially the façades of the palace were unified by a giant order of Ionic pilasters framing huge windows. It is believed that the decoration works of the palace were performed by Michelangelo Palloni and Giovanni Pietro Perti who was the architect of the palace.
The Polish–Lithuanian rulers used to stay in the palace during their visits in the city after the Royal Palace was damaged. The Russian tsar Peter the Great stayed and had his headquarters established here in 1705 and 1709.
After Słuszko's death the palace was owned by the Puzyna princely family since 1727 and by the Potocki family since 1745. The Piarist monks bought the palace in 1756 and established a collegiate and a printing house. Later it was bought by Michał Kazimierz Ogiński in 1766 and reconstructed by Pietro Rossi. The palace was confiscated by the tsarist government in 1794 and transformed into an apartment house. It housed a brewery of Dominik Zajkowski from 1803 until 1831 when the palace was taken by tsarist military. The building was rearranged, the floors were redivided into four, and the palace served as a military prison since 1872. The rich original interior and exterior of the palace have not survived.
Nowadays the palace houses the Lithuanian Academy of Music and Theatre. In the meantime the outhouses are undergoing the restoration and the main palace is planned to come next. The palace is planned to regain its original two main floors layout and original Baroque style windows.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.
