Modern-day towers of Babylon, ancient Egyptian tombs, subterranean tunnels beneath the sea and vast bridges spanning wide rivers. From colossal canyons and celestial fireworks to an underwater paradise, imperial palace and a symbol of the free world that was a present from France to the United States of America: all of these are Wonders of the World...but how many of us realise there are actually 28 Wonders of the World; seven Ancient, seven Modern, seven Natural, along the 'standard' seven, let alone could set about naming them all?

And just what is it that makes a Wonder of the World so wonderful?

• Should there be only one list of the top seven wonders, and which of those would make your list?

• Why seven? What makes seven such a wondrous number?

• What do you think are the requirements to be considered as or as a contender for a Wonder of the World title?

• Are there any not on the Wonders of the World lists you'd consider a 'Wonder', and why?

• Are there any current Wonders of the World you think don't deserve their title?

• Have you ever seen a Wonder of the World up close and personal? Was it wonderful?

Whatever your opinion, we invite you to share it with us in this week's Talking Point. The best contributions may be used for a future Edited Entry.
