The Forum of Augustus is one of the Imperial forums of Rome, Italy, built by Augustus. It was built in 42 BC to commemorate Augustus' victory at the Battle of Philippi over the assassins of Julius Caesar.
The Temple of Mars Ultor stands in the forum. It was inaugurated in 2 BC and it came to function as the focal point of Roman military strategy. For example, Augustus decreed that it should be the meeting place for the Senate when decisions of war were taken. The temple was also the place where young Roman males were ceremoniously given their adult toga, thus becoming eligible for military service, and it was the official departure point for commanders embarking on military service in the empire.
Behind the temple stands a 30 m high tufa wall which is topped with white travertine. It was constructed to separate the Forum from the hill residences behind it and to act as a firewall should a fire start in this densely-populated area of the city. In the 1st century AD Tiberius added two arches to the temple sides in honour of his two sons Drusus the Younger and Germanicus but these have now been lost except for the foundations of one. In the 2nd century Hadrian repaired parts of the building but from the 5th century the building went into decline and blocks began to be re-used in other building projects.
From the 12th century soil was added to the site and the area used for agriculture, however, as the drains were then blocked, a marsh formed until the area was drained in the 16th century.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.
