The Theatre of Dionysus Eleuthereus is a major theatre in Athens, built at the foot of the Athenian Acropolis. Dedicated to Dionysus, the god of plays and wine, the theatre could seat as many as 17,000 people with excellent acoustics, making it an ideal location for ancient Athens' biggest theatrical celebration, the Dionysia. It was the first theatre ever built, cut into the southern cliff face of the Acropolis, and supposedly birthplace of Greek tragedy. The remains of a restored and redesigned Roman version can still be seen at the site today. It is sometimes confused with the later, smaller, and better-preserved Odeon of Herodes Atticus, located nearby on the southwest slope of the Acropolis.
The site has been used as a theatre since the sixth century BC. The existing structure dates back to the fourth century BC but had many other later remodellings. The only certain evidence of this early theatre consists of a few stone blocks that were reused in the 100 century BC.
By the end of the fifth century BC, some of the wooden constructions had been replaced with stone. The Theatre of Dionysus in its present general state dates largely to the period of the Athenian statesman Lycurgus (ca. 390-325/4 BC), who, as overseer of the city's finances and building program, refurbished the theatre in stone in monumental form. The fourth century theatre had a permanent stage extending in front of the orchestra and a three-tiered seating area (theatron) that stretched up the slope.
The Theatre of Dionysus underwent a modernization in the Roman period, although the Greek theatre retained much of its integrity and general form. An entirely new stage was built in the first century CE, dedicated to Dionysus and the Roman emperor Nero. By this time, the floor of the orchestra had been paved with marble slabs, and new seats of honor were constructed around the edge of the orchestra. Late alterations carried out in the third century AD by the archon Phaedrus included the re-use of earlier Hadrianic reliefs, which were built into the front of the stage building.[The remains of a restored and redesigned Roman version of the theatre can still be seen at the site today.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.
