Pollentia was founded by the consul Qintus Caecilius Metellus in 123 BC in the strategic location between the bays of Pollenca and Alcudia. It was the most important city in the Balearics duing the Roman period and covered an area of 15-20 hectares.
This area suffered a devastating fire in the 3rd century AD, but the city was not depopulated, since the construction of a fortification in the fifth century AD has been documented in the same forum. In the following centuries, the Pollentia site was partially or totally unpopulated, with the Christian medieval population settling down a bit further north, in the present town of Alcúdia. Excavations, since the 16th century, but especially since the beginning of the 20th century, have occurred mainly in the area of Sa Portella (a residential district), Camp d'en França (the city forum and the tabernae), and in the Roman theater.
There is also a museum, the Museu Monografic de Pollentia in the centre of Alcudia (by the church) which displays many of the objects found on the site.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.
