The present Naples cathedral was commissioned by King Charles I of Anjou. Construction continued during the reign of his successor, Charles II (1285-1309) and was completed in the early 14th century under Robert of Anjou. It was built on the foundations of two palaeo-Christian basilicas, whose traces can still be clearly seen. Underneath the building excavations have revealed Greek and Roman artifacts. The Archbishop's Palace adjoins the cathedral.
The main attraction of the interior is the Royal Chapel of the Treasure of San Gennaro, with frescoes by Domenichino and Giovanni Lanfranco, altarpieces by Domenichino, Massimo Stanzione and Jusepe Ribera, the rich high altar by Francesco Solimena, the bronze railing by Cosimo Fanzago and other artworks, including a reliquary by 14th-century French masters.
Other artworks include an Assumption by Pietro Perugino, canvasses by Luca Giordano and the palaeo-Christian baptistery, with mosaics from the 4th century. The main chapel is a restoration of the 18th century, with a Baroque relief by Pietro Bracci. The Minutolo Chapel, mentioned in Boccaccio's Decameron, has 14th-century frescoes.
The crypt is by the Lombard Tommaso Malvito. The façade was reworked by Enrico Alvino in the late 19th century, but retains the 15th century portal, including some sculptures by Tino da Camaino.
References:Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
