Munkholmen is an islet which has served as a place of execution, a monastery, a fortress, prison, and a World War II anti-aircraft gun station.
In the years prior to the founding of the city of Trondheim in 997 by Viking King Olav Tryggvason, Munkholmen was used as an execution site by the Jarls of Lade. The arrival of Olav Tryggvason to Norway in 995 coincided with a revolt against Haakon Sigurdsson, who was killed by Tormod Kark. The severed heads of both Haakon and Kark were placed on stakes on Munkholmen facing out into the fjord to serve as a warning to visitors. Legend has it that before entering Trondheim, visitors were made to spit on these heads as a tribute to King Olav I of Norway. The tradition of displaying the severed heads of criminals and political opponents was continued for some time, but the heads were now placed so that they faced the city of Trondheim to deter its citizens from committing crimes.
In the early 12th century, and possibly even earlier, Benedictine monks lived on the island in Nidarholm Abbey. Local stories claim the monastery was quite lively and that on several occasions requests came from the mainland to keep the noise down. By the time Lutheran Protestantism came to Trondheim, the monastery had fallen into decay.
Construction of a fort on the island began in 1658. When it was completed in 1661, the fort was also used as a state prison for society's rejects. Count Peder Griffenfeld, Munkholmen's most famous prisoner, was transferred from the fortress of Copenhagen in 1671. Griffenfeld was kept at Munkholmen for 18 years, after which he was released, having contracted a terminal illness. The fort remained in operation until 1893.
Nazi Germany invaded and occupied Norway in 1940. After capturing Trondheim early on in the Norwegian Campaign, the Germans quickly established a submarine base, exploiting the natural protection provided by the fjord. At this time, Munkholmen was fitted with anti-aircraft weaponry. A large portion of the fort was retrofitted to hold ammunition, and the flooring planks were nailed in with wooden nails to prevent explosions caused by soldiers' boots striking metal nails. The German occupying forces remained in Norway until the end of the war in Europe in May 1945. Remnants of the installation still exist in the upper levels of the fort.
Today, Munkholmen is a popular summertime tourist attraction and hangout for residents of Trondheim. From May to September, boats depart from Ravnkloa on a regular basis. Once on the island, visitors can take a guided tour (in English and Norwegian) or roam freely. There's also a small cafe/restaurant available.References:
Angelokastro is a Byzantine castle on the island of Corfu. It is located at the top of the highest peak of the island"s shoreline in the northwest coast near Palaiokastritsa and built on particularly precipitous and rocky terrain. It stands 305 m on a steep cliff above the sea and surveys the City of Corfu and the mountains of mainland Greece to the southeast and a wide area of Corfu toward the northeast and northwest.
Angelokastro is one of the most important fortified complexes of Corfu. It was an acropolis which surveyed the region all the way to the southern Adriatic and presented a formidable strategic vantage point to the occupant of the castle.
Angelokastro formed a defensive triangle with the castles of Gardiki and Kassiopi, which covered Corfu"s defences to the south, northwest and northeast.
The castle never fell, despite frequent sieges and attempts at conquering it through the centuries, and played a decisive role in defending the island against pirate incursions and during three sieges of Corfu by the Ottomans, significantly contributing to their defeat.
During invasions it helped shelter the local peasant population. The villagers also fought against the invaders playing an active role in the defence of the castle.
The exact period of the building of the castle is not known, but it has often been attributed to the reigns of Michael I Komnenos and his son Michael II Komnenos. The first documentary evidence for the fortress dates to 1272, when Giordano di San Felice took possession of it for Charles of Anjou, who had seized Corfu from Manfred, King of Sicily in 1267.
From 1387 to the end of the 16th century, Angelokastro was the official capital of Corfu and the seat of the Provveditore Generale del Levante, governor of the Ionian islands and commander of the Venetian fleet, which was stationed in Corfu.
The governor of the castle (the castellan) was normally appointed by the City council of Corfu and was chosen amongst the noblemen of the island.
Angelokastro is considered one of the most imposing architectural remains in the Ionian Islands.
