Rising out on a rocky crag above the confluence of two rivers near the Guadarrama mountains, the Alcázar of Segovia is one of the most distinctive castle-palaces in Spain by virtue of its shape – like the bow of a ship. The Alcázar was originally built as a fortress but has served as a royal palace, a state prison, a Royal Artillery College and a military academy since then. It is currently used as a museum and a military archives building.
The Alcázar, like many fortifications in Spain, started off as Roman fort, but apart from the foundations, little of the original structure remains. A Muslim era fort, which was itself largely replaced by the present structure, was built by the Berber Almoravid dynasty. The first reference to this particular "alcázar" was in 1120, around 32 years after the city of Segovia returned to Christian hands. It can be concluded that prior to Alfonso VIII's reign, the Muslim era structure was no more than a wooden fort built over the old Roman foundations. Alfonso VIII and his wife, Eleanor of England, made this alcázar their principal residence and much work was carried out to erect the beginnings of the stone fortification we see today.
The Alcázar of Segovia was one of the favorite residences of the monarchs of Castile in the Middle Ages, and a key fortress in the defence of the kingdom. It was during this period that most of the current building was constructed by the Trastámara dynasty.
In 1258, parts of the Alcázar had to be rebuilt by King Alfonso X after a cave-in and the Hall of Kings was built to house Parliament soon after. However, the single largest contributor to the continuing construction of the Alcázar is King John II who built the "New Tower" (John II tower as it is known today).
The next major renovation at the Alcázar was conducted by King Philip II after his marriage to Anna of Austria. He added the sharp slate spires to reflect the castles of central Europe. In 1587, architect Francisco de Morar completed the main garden and the School of Honor areas of the castle.
The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
