Rjukan-Notodden Industrial Site

Rjukan, Norway

Rjukan–Notodden Industrial Heritage Site is created to protect the industrial landscape around Lake Heddalsvatnet. The landscape is centered around the plant built by the Norsk Hydro to produce fertilizer from atmospheric nitrogen. The complex also includes hydroelectric power plants, transport systems, including railways, transmission lines and factories, and workers' accomodation and social institutions in the towns of Notodden and Rjukan.

In the 1900s, Norway experienced rapid industrial development through the availability of cheap hydroelectric power. Kristian Birkeland developed a method to extract nitrogen from the air, which, after an initial trial in Notodden in 1907, looked superior to existing technologies. Nitrogen was needed to produce fertilizers. Norsk Hydro was founded in 1905, and industrial development began in the Eastern Telemark region, previously an underdeveloped and underpopulated agricultural area. To produce fertilizers, it was essential to build factories, power stations, infrastructure for workers, as well as facilities for exporting the production. The fertilizers, artificial salpetre, eventually surpasses the Chilean naturally mined salpeter, at the time the most widely used fertilizer.

At the beginning of construction, in 1907, the power was provided by the Svelgfoss Hydroelectric Power Station, which at the time was the largest in Europe and the second larges at the world. The station is still in operation. Subsequently, two more station were built. Vemork, built on a waterfall near Rjukan, in 1911 was the largest power station in the world. A plant producing heavy water and most famous for the 1943 sabotage events (Operation Gunnerside) was built nearby. The original building of the station has been destroyed, but the station is in operation. Another power plant, Såheim Hydroelectric Power Station, started operation in Rjukan in 1915. The building survived but the station operates elsewhere.

One of the 36 towers of the salpetre factory's towerhouse, which was in operation between 1911 and the 1980s, has been conserved and is protected as a cultural monument.

In 1925, 80% of all apartments in Rjukan (1230 in total) were controlled by the Norsk Hydro. red brick apartment buildings dominated, others were houses with individual gardens.

The site was placed on the tentative World Heritage list on 26 November 2011 together with the Odda–Tyssedal Industrial Heritage Site. In 2015 it was placed on the World Heritage list.

Good service, lots of info, lies next to the village square, no internet there. However everything is within walking distance. In the winter the famous sun mirror shines down next to the tourist office in the middle of the square. Also pay attention to the original Norsk hydro heavy water barrels on the outside. They really should have some wifi there and some sitting place where visitors can sit and review the brochures and check that up on the www, so thats a major minus

Royal Palace of Naples

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.
