nice list of cool man-made marvels here to keep in mind for your travels, some you know well and many you may have never heard of:

^^ Many of those are not architectural marvels IMO-Graceland is an architectural marvel? But still an interesting list. That library in Balltimore reminded me of the old Palace Hotel in SF. before the earthquake. And some really are marvels.

 

I also now cannot stand any of the Gehry "crumpled cans" architecture. If they were choosing for every state, then Ohio should have been Serpent Mound-just about the oldest manmade thing in the state and a marvel as well.

 

Worldwide there are so many from the Taj Mahal to Machu Picchu, The Great Wall to Holland's flood control system. Just too many to list or even ever visit.

 

I wish we could get at least one for Columbus.
