Fredriksten Fortress was constructed by Denmark-Norway in the 17th century as a replacement for the border fortress at Bohus, which had been lost when the province of Bohuslän was ceded to Sweden by the terms of the Treaty of Roskilde in 1658. The fortress was named after King Fredrik III of Denmark and Norway. Fredriksten took part to the battle first time two years later, in January of 1660, when the Swedish forces attacked Halden for the third time. After the attempt to storm the fortifications was unsuccessful, the Swedes prepared a regular siege. On 22 February 1660 the Swedes again were forced to retreat to Bohuslen until they heard that their king Charles X had died.
The existing star shaped fortress complex was upgraded during the period of peace between 1661–1675. In 1673 Denmark dispatched Ulrik Frederik Gyldenløve as statholder to Norway to organize the military forces and strengthen the defenses of the kingdom. After a tour of facilities, he recommended further upgrades to both the fortress and the military forces. In the summer of 1675, 1800 men were kept at work on the fortresses at Akershus, Fredrikstad, and Fredrikshald. Fredriksten was expanded from 1682–1701. It now included three outer fortifications: Gyldenløve, Overberget and Stortårnet.
At the close of the Great Northern War Charles XII of Sweden attempted to take Frederiksten by storm on 4 July 1716. His troops took the town after fierce fighting, but the citizens set fire to their own houses, forcing Charles, unable to take the fortress, to retreat and await the arrival of heavy siege guns. Unfortunately for the invading army the entire Swedish transport fleet was captured or destroyed by the Norwegian naval hero Tordenskjold at the Battle of Dynekilen in Bohuslen. Running low on supplies, Charles retreated hastily across the Svinesund and burned the bridges behind him. By 12 July 1716 all Swedish troops had been withdrawn from the area around Fredriksten.
In the Autumn of 1718 Charles once more attacked Norway, intending to first capture Halden to be able to sustain a siege of Akershus. The 1,400 strong garrison of Frederiksten fought ferociously to hold back the invasion, but suffered a severe setback when, on 8 December the forward fortification Fort Gyldenløve fell. Encouraged by their very hard-fought success the Swedish army intensified their efforts against the main fort. The Swedish trenches had almost reached the main fortification walls when on the evening of 11 December 1718, a bullet struck and killed Charles XII while he inspected the work. The death of the king effectively ended the attack on Fredriksten and the invasion was called off, leading to the conclusion of the war. A memorial is located in the park named in his memory where the Swedish king fell, just in front of the fortress.
In 1788 the fortress served as a staging area for a mock attack on Sweden during the Theater War. During The Napoleonic Wars the fortress was bombarded in 1814 but not captured. The advancing Swedish forces of Charles John passed it on their advance, leaving a force that tried to force its surrender, but the fortress and its commander kept the ground. It was turned over to Sweden after the Convention of Moss. The old fortress flag from 1814, taken by the Swedish troops and not returned to Norway until 1964, is preserved in the present day museum located inside the inner fortress.
After 1905 the fortress lost all military significance, but it still hosted various units. As of today the Norwegian defence logistics and administrative college is situated by the fortress. The fortress also hosts several museums and art exhibitions. During the summer season outdoor concerts are arranged with both classic and contemporary music.References:
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
