We are most of us familiar with the 7 wonders of the ancient world:

1.The great pyramid of Egypt
2. The Hanging Gardens of Babylon
3. The statue of Zeus at Olympia
4. That well-known temple of Artemis at Ephesus
5. One mausoleum at Halicarnassus
6. Rhode’s Colossus …
7. .. and the lighthouse of Alexandria.

Only one of which – the pyramid – still remains.
