What is the parthenon built for?
It was built as a temple to the patron goddess of Athens, Athena. She was also known as Athena Parthenos or Athena the maiden which is why its called the Parthenon. It was also built to celebrate a significant victory by Athens over the Persian army who had almost beaten the Athenian when they invaded Athens a few years before. Many Athenian buildings were destroyed by fire during the Persian war and the Athenian ruler Pericles launched a big programme of building to make the city beautiful.
