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:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
