The passage discusses the selection of the Seven Wonders of the Ancient World by ancient Greeks. After much debate over which structures to include, the Greeks agreed on a list of seven unique and impressive structures from history, including the Great Pyramid at Giza, Hanging Gardens of Babylon, Statue of Zeus at Olympia, Temple of Artemis at Ephesus, Mausoleum at Halicarnassus, Colossus of Rhodes, and Lighthouse at Alexandria.
