During the High Middle Ages the Freiherr von Oberhofen built Balm Castle on a hill above the village. In 1200, a daughter of the family, Ita, married into the von Eschenbach family and gave this family the castle and village. In the 13th century they began a new, moated castle on the shores of Lake Thun. One of the last owners of the castle, Walter IV von Eschenbach, was assassinated along with King Albert I in 1308 by Albert's nephew John. In 1306 the von Eschenbach family was forced to sell Oberhofen and the castle to the Habsburgs. The Habsburgs appointed a succession of vassals to administer the area for them, especially the Kyburgs who also owned Thun Castle. Following the Kyburg defeat in the Burgdorferkrieg of 1383-84 and the decisive Habsburg defeat at the Battle of Sempach in 1386, Bern began to expand into the Austrian lands in the Bernese Oberland. They occupied Oberhofen in 1386 and were finally able to purchase or usurp all the land and rights from every feudal land holder in 1397. In the following year they sold the castle and Oberhofen Herrschaft to Ludwig von Seftigen, a citizen of Bern.
Over the following centuries the town, castle and herrschaft passed through several Bernese patrician families. After the male line of the von Erlach family in Oberhofen died out in 1652, Bern acquired the castle and lands. They created the bailiwick of Oberhofen and converted Oberhofen Castle into the administrative center for the bailiwick. Following the 1798 French invasion, Oberhofen am Thunersee became part of the Helvetic Republic Canton of Oberland. After the collapse of the Republic and 1803 Act of Mediation it joined the newly created Thun District.
The castle passed into private hands after 1803 and had several owners in the following years. In 1849-52 the Pourtàles family renovated and expanded the castle to its present appearance. In 1940 the American William Maul Measy established the Oberhofen Castle foundation to administer and maintain the castle. In 1952 it became a part of the Historical Museum of Bern and two years later they opened a branch in the castle.
The central keep probably dates from around 1200. The rest of the castle developed in the following centuries around this ancient keep. A chapel was added to the first floor of the keep on the lake side in 1473. Perhaps at the same time a tower was built in the lake. The lake tower appears in an illustration of the castle in 1680.
After Bern took over the castle from the von Erlach family it became the seat of a Bernese bailiff and was expanded. By 1700, the Bernese renovations were mostly complete. The original tower was partly surrounded by new buildings done in the Bernese Baroque style. On the lake side the Garden Room was built and the water tower demolished. Over the next centuries, the castle remained virtually unchanged until the castle went back into private ownership. The Neuchâtel-Prussian Count de Pourtàles rebuilt the castle in a Romantic style between 1849 and 1852. The north-eastern side of the keep was rebuilt, as was the entire western facade.
A 2.5 ha park was added south of the castle. The water tower was rebuilt and crowned with a fanciful spire. In the interior of the castle, a dining hall and grand hall were built. On the upper floors the ornate library and a Turkish smoking room were added. The Turkish smoking room was based on similar rooms from wealthy houses in Cairo and built in 1853 to 1855 on plans from the Bernese architect Theodor Zerleeder. Count Albert Alexander de Pourtalè had spent several years in Istanbul as a Prussian diplomat.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.
