There is nothing so beautiful by the hand of man, as a garden. Philadelphia is blessed with some of the nation's greatest gardens and arboretums, including the incomparable Longwood Gardens, Fairmount Park, Morris Arboretum, Winterthur, Chanticleer, Scott Arboretum, Bartram's Gardens and the Tyler Arboretum.
We are also blessed with other landscape constructions; some of the most beautiful and testing inland golf courses in America as well. The combination of function and aesthetic in golf courses can rise to the highest levels of all endeavors.
Many in the know speak of bridges as being the ultimate expression of engineering and art. There is something about seeing the Verrazano Narrows Bridge or Golden Gate Bridge for the first time. Driving over a bridge is scary and thrilling at the same time. Being in a car over the old bridge out of Charleston, SC can be very scary...especially late on a St. Patrick's Day evening with a designated driver, of course.
I agree, John. Dams are wonderful structures. And of course there is building architecture...The Chrysler Building, Frank Furness's work, Horace Trumbauer, Duhring, Okie & Ziegler, etc.
A highway and overpass? Not in my top 100 (if I ever came up with such a list).
