Wonders of the World - iPad Edition app for iPhone and iPad

The Seven Wonders of the Ancient World is the first known list of the most remarkable creations of classical antiquity, and was based on guide-books popular among Hellenic sight-seers and only includes works located around the Mediterranean rim. The number seven was chosen because the Greeks believed it to be the representation of perfection and plenty. Many similar lists have been made.
