4. Detailed explanation The Parthenon is a temple on the Athenian Acropolis, Greece, dedicated to the maiden goddess Athena, whom the people of Athens considered their patron deity. Its construction began in 447 BC when the Athenian Empire was at the height 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. 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. In the 5th 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. Since 1983, the Greek government has been committed to the return of the sculptures to Greece, so far with no success.
