The site of the Simancas castle was at one time a Moorish fortress. In the 15th century the House of Enríquez constructed a new fortification on top of the existing ruins, restored the Moorish walls, and added a chapel. The new castle was seized by the Spanish Crown during the reign of the Catholic Monarchs and turned into a prison. In 1540 the Archivo General de Simancas was established in the castle, the first official archive of Castile. Felipe IItransformed the castle into General Archive of the Kingdom, which housed one of the most important archives in Europe with 35 million documents. The castle was put under the protection of the Spanish government in 1949. In 1952 renovations were enacted to reduce risk to the archives. The castle is now open to tourists and researchers.
The castle's foundation, walls, battlements, gates, and bridges all date back to the late 15th century, mostly attributed from 1467 to 1480. The end of the reconquesta in 1492 ended the immediate need for a large defensive fortification, and as such the castle's various reconstructions molded it into an administrative building. Later additions to the castle incorporate aspects of the Herrerian style of architecture. The current archive housed within the castle has been protected with fireproofing measures, and the 15th century chapel built by the Enríquez has been restored.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.
