St. Hedwig's Cathedral is the seat of the archbishop of Berlin. It was built in the 18th century as the first Catholic church in Prussia after the Protestant Reformation by permission of King Frederick II. The intention of Frederick was to offer the numerous Catholic immigrants who had arrived in Berlin, especially those from Upper Silesia, a place of worship. The church was therefore dedicated to the patron of Silesia and Brandenburg, Saint Hedwig of Andechs. The building was designed by Georg Wenzeslaus von Knobelsdorff modeled after the Pantheon in Rome and construction started in 1747, interrupted and delayed several times due to economic problems. It was not opened until November 1, 1773 when the king's friend, Ignacy Krasicki, then Bishop of Warmia (later Archbishop of Gniezno), officiated at the cathedral's consecration.
After the Kristallnacht pogroms that took place over the night of 9–10 November 1938, Bernhard Lichtenberg, a canon of the cathedral chapter of St Hedwig since 1931, prayed publicly for Jews in the evening prayer following. Lichtenberg was later jailed by the Nazis and died on the way to the concentration camp at Dachau. In 1965 Lichtenberg's remains were transferred to the crypt at St. Hedwig's.
The cathedral burned down completely in 1943 during air raids on Berlin and was reconstructed from 1952 up to 1963.
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.
