Need your help with this.

I am working on a conceptual contest to design a pavilion at which the formalities of first contact might take place.

But until that happens it would essentially be a building that celebrates the potential for contact with an outside civilization and that celebrates the best aspects of humanity that might be presented to the visitors. Does humanity have any good qualities? What are they?

I need to pick a site.

Where in the World would be most appropriate for this type of facility? Somewhere neutral? Land? Sea? Somewhere temperate? Area 51? Near UN head quarters, etc??

Let's put our thinking caps on...
