The Great Pyramid at Giza is both the oldest ancient wonder and the only one still standing today. It was built as a mausoleum for the pharaoh Khufu around 2650 BC and for over 4,000 years remained the world's tallest structure.
According to legend, 6th-century Babylonian King Nebuchadnezzar had a colossal maze of waterfalls and dense vegetation planted across his palace for a wife, who missed her lush homeland. Archaeologists still debate the garden's existence.
The Mausoleum of Maussollos, or Mausoleum of Halicarnassus was a tomb built between 353-350 BC at Halicarnassus (present Bodrum, Turkey), for Mausolus a provincial king in the Persian Empire, and Artemisia, his wife and sister. It was designed by the Greek architects Satyrus and Pythius.
