Seven Wonders

I want to visit all seven wonders of Britain. I’ve done four leaving only these to visit:

1. Hadrian’s Wall, Northumberland
2. Eden Project, Cornwall
3. Windsor Castle, Berkshire

The Guardian also lists The Angel of the North as the eighth wonder. I haven’t seen that either! If you’re interested, the others (that I have seen) are:

1. Big Ben, London
2. London Eye
3. Stonehenge, Wiltshire
4. York Minster, Yorkshire
