On Pittsburgh's Mount Washington which overlooks the confluence of the Allegheny, Monongahela, and Ohio Rivers, one can find a parklet called "Point of View" which is a part of the Grand View Scenic Byway Park.
The park got its name from the bronze sculpture Point of View, by James A. West. Point of View depicts a face-to-face meeting between George Washington (yes, that George Washington) and the Seneca leader Guyasuta that took place in October, 1770.
If you step on the other side of the sculpture, there's a pretty decent view of the rivers and the city below.
