Any (serious) ideas? Mine would probably include:
The Moonbridge of Silverymoon
Candlekeep Library
The mythal of Myth Drannor
Host Tower of the Arcane
The Standing Stone
....?

Evermeet?

The ruins in the desert of, i think it's, Anuroch?

I think that the carcathen in the west of the forgotten realms in the Trackless sea would be mine:<}

I'd have to agree with Reeky there, that's a pretty good one as well.

How about the dungeon of Undermountain?

The Spirit Soaring of Snowflake mountains

Ex-Edificant library, the home to the order of Deneir, just to advance Erran's Candlekeep idea :)

I'd say for Evermeet to be the greatest wonder in the realms
