The Patriarchal Cathedral Basilica of Saint Mark (Basilica di San Marco is the most famous of the Venice's churches and one of the best known examples of Italo-Byzantine architecture. It lies at the eastern end of the Piazza San Marco, adjacent and connected to the Doge's Palace. Originally it was the chapel of the Doge, and has only been the city's cathedral since 1807, when it became the seat of the Patriarch of Venice, archbishop of the Roman Catholic Archdiocese of Venice, formerly at San Pietro di Castello.
For its opulent design, gold ground mosaics, and its status as a symbol of Venetian wealth and power, from the 11th century on the building has been known by the nickname Chiesa d'Oro (Church of gold).
The first church was a building next to the Doge's Palace in 828-832, when Venetian merchants stole the supposed relics of Mark the Evangelist from Alexandria. The church was burned in a rebellion in 976, when the populace locked Pietro IV Candiano inside to kill him, and restored or rebuilt in 978. Nothing certain is known of the form of these early churches. The present basilica was constructed probably between 1063-1093. In 1106 the church, and especially its mosaics, were damaged by a serious fire in that part of the city.
The basic structure of the building has not been much altered. Its decoration has changed greatly over time, though the overall impression of the interior with a dazzling display of gold ground mosaics on all ceilings and upper walls remains the same. The succeeding centuries, especially the period after the Venetian-led conquest of Constantinople in the Fourth Crusade of 1204 and the 14th century, all contributed to its adornment, with many elements being spolia brought in from ancient or Byzantine buildings, such as mosaics, columns, capitals, or friezes. Gradually, the exterior brickwork became covered with marble cladding and carvings, some much older than the building itself, such as the statue of the Four Tetrarchs. The latest structural additions include the closing-off of the Baptistery and St Isidor's Chapel (1300s), the carvings on the upper facade and the Sacristy (1400s), and the closing-off of the Zen Chapel (1500s).
The facade features five portals decorated in splendid marbles and mosaics, and with a terrace dividing it into two halves. On the terrace stand Four Horses of gilded copper (copies - the originals are now preserved inside) that were sent from Constantinople to Doge Enrico Dandolo in 1204.
Splendid mosaics in the atrium relate the stories of the Bible. The imposing interior in the form of a Greek cross contains a wealth of paintings and sculptures. Of particular interest are mosaics of Veneto-Byzantine origin, some of them reconstructed from drawings by Titian, Tintoretto and Veronese.
The treasury contains a unique collection of Byzantine portable objects in metalwork, enamel and hardstone carving. Most of them were looted from Constantinople after the Fourth Crusade (although there was a serious fire in the treasury in 1231), with probably a new influx after the 'Franks' were expelled in 1261. Thereafter most objects were made locally, though there are also important Islamic works, especially in rock crystal, and some from Northern Europe. Selections have toured internationally.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.
