The Parthenon is a former temple, on the Athenian Acropolis, dedicated to the goddess Athena, whom the people of Athens considered their patron. Construction began in 447 BC when the Athenian Empire was at the peak of its power. It was completed in 438 BC although decoration of the building continued until 432 BC. It is the most important surviving building of Classical Greece, generally considered the zenith of the Doric order. The decorative sculptures are considered some of the high points of Greek art. The Parthenon is regarded as an enduring symbol of Ancient Greece, Athenian democracy and western civilization, and one of the world's greatest cultural monuments. To the Athenians who built it, the Parthenon and other Periclean monuments of the Acropolis, were seen fundamentally as a celebration of Hellenic victory over the Persian invaders and as a thanksgiving to the gods for that victory. The Greek Ministry of Culture is currently carrying out a programme of selective restoration and reconstruction to ensure the stability of the partially ruined structure.
The Parthenon itself replaced an older temple of Athena, which historians call the Pre-Parthenon or Older Parthenon, that was destroyed in the Persian invasion of 480 BC. The temple is archaeoastronomically aligned to the Hyades. Like most Greek temples, the Parthenon served a practical purpose as the city treasury. For a time, it served as the treasury of the Delian League, which later became the Athenian Empire. In the final decade of the sixth century AD, the Parthenon was converted into a Christian church dedicated to the Virgin Mary.
After the Ottoman conquest, it was turned into a mosque in the early 1460s. On 26 September 1687, an Ottoman ammunition dump inside the building was ignited by Venetian bombardment. The resulting explosion severely damaged the Parthenon and its sculptures. From 1800 to 1803, Thomas Bruce, 7th Earl of Elgin removed some of the surviving sculptures with the alleged permission of the Ottoman Empire. These sculptures, now known as the Elgin Marbles or the Parthenon Marbles, were sold in 1816 to the British Museum in London, where they are now displayed.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.
