Castel Sant'Elmo is a medieval fortress located on a hilltop near the Certosa di San Martino, overlooking Naples. Documents date a structure at the site from 1275, from the era of Charles d'Anjou. Known originally as Belforte, it was likely a fortified residence, surrounded by walls, its entrance gate marked by two turrets. In 1329, using designs by the Sienese architect Tino da Camaino, king Robert of Naples enlarged the fortress.
The Angevin fortress was severely damaged in an earthquake in 1456, which demolished the external walls and the towers. The Aragonese rulers of Naples, and notably Don Pedro de Toledo, the first governor and cousin of the Viceroy, included it in a comprehensive scheme designed to fortify the land perimeter of the city, based on four separate strongholds. Castel Sant'Erasmo acquired its hexagonal star shape between 1537 and 1547 under the designs of Pedro Luis Escrivafrom Valencia, a military architect. The daring hexagonal shape drew fierce criticism from his contemporaries, to such an extent that in 1538 Escriva defended his design in a published Apologia.
The castle served as an autonomous military outpost, with a governor who had absolute authority over both military and civilian matters. Around the parade grounds were situated the officers' quarters, chaplain's house, a church (1547) designed by the Spanish architect Pietro Prato, and the surviving buildings from the Angevin Belforte. Don Pedro de Toledo's funerary monument (1588) is found in the sacristy of the church.
In 1587 the munitions depot of the castle was struck by lightning, and exploded, destroying the church, the chaplain's house and the officers' quarters. Reconstruction was carried out between 1599 and 1601 under the architect Domenico Fontana. Despite successive rebuildings over the centuries, the castle conserves its original structure. Built of volcanic tufa, it overlords over Naples, and ever since the famous Tavola Strozzi incident (late 15th century), for centuries it was a symbol and bastion of government oppression. In 1604 it was used to imprison Tommaso Campanella, branded as a heretic, and in 1799 the patriots of the Neapolitan Revolution, including Gennaro Serra, Mario Pagano and Luigia Sanfelice. With the departure of the Bourbon garrison in 1860, it remained a military prison until 1952, when the prison was transferred to Gaeta.
Today there are several permanent art exhibits in the castle. One of the most unique is the railing featuring an inscription in braille which was installed in 2015. The railing, which is more than 30 feet long and dotted with braille letters, is above the drill grounds on the northernmost wall of the castle near the west corner.References:
Bergenhus fortress is one of the oldest and best preserved castles in Norway. It contains buildings dating as far back as the 1240s, as well as later constructions built as recently as World War II. The extent of the enclosed area of today dates from the early 19th century. In medieval times, the area of the present-day Bergenhus Fortress was known as Holmen (The islet), and contained the royal residence in Bergen, as well as a cathedral and several churches, the bishop's residence, and a Dominican monastery. Excavations have revealed foundations of buildings believed to date back to before 1100, which might have been erected by King Olav Kyrre. In the 13th century, until 1299, Bergen was the capital of Norway and Holmen was thus the main seat of Norway's rulers. It was first enclosed by stone walls in the 1240s.
Of the medieval buildings, a medieval hall and a defensive tower remain. The royal hall, today known as Haakon's Hall, built around 1260, is the largest medieval secular building in Norway. The defensive tower, known in the Middle Ages as the keep by the sea, was built around 1270 by King Magnus VI Lagabøte, and contained a royal apartment on the top floor. In the 1560s it was incorporated by the commander of the castle, Erik Rosenkrantz, into a larger structure, which is today known as the Rosenkrantz Tower.
In the Middle Ages, several churches, including the Christ Church, Bergen's cathedral, were situated on the premises. These however were torn down in the period 1526 to 1531, as the area of Holmen was converted into a purely military fortification under Danish rule. From around this time, the name Bergenhus came into use. Building work on the Christ Church probably started around 1100. It contained the shrine of saint Sunniva, the patron saint of Bergen and western Norway. In the 12th and 13th centuries it was the site of several royal coronations and weddings. It was also the burial site of at least six kings, as well as other members of the royal family. The site of its altar is today marked by a memorial stone.
In the 19th century, the fortress lost its function as a defensive fortification, but it was retained by the military as an administrative base. After restoration in the 1890s, and again after destruction sustained during World War II, Bergenhus is today again used as a feast hall for public events. During World War II, the German navy used several of its buildings for their headquarters, and they also constructed a large concrete bunker within the fortress walls. The buildings, including the Haakon's Hall, were severely damaged when a Dutch ship in the service of the German navy, carrying approximately 120 tons of dynamite, exploded on 20 April 1944 in the harbour just outside the fortress walls, but the buildings were later restored.
Bergenhus is currently under the command of the Royal Norwegian Navy, which has about 150 military personnel stationed there. The fortifications Sverresborg fortress and Fredriksberg fortress also lie in the centre of Bergen. Haakon's Hall and the Rosenkrantz Tower are open for visits by the public. Koengen, the central part of Bergenhus Fortress is also known as a concert venue.
