4. The Big Savage Tunnel

The Big Savage Tunnel is yet another remnant of the Western Maryland Railroad which earns a spot on my 7 man-made wonders of the PA Laurel Highlands list.

The 3,294 foot long tunnel was a critical link in that rail line, until the entire line was abandoned in 1975.

The tunnel fell into a state of disrepair until the late 1990s when the Allegheny Trail Alliance stepped in to restore the tunnel as part of a greater rails-to-trails initiative.

5. Kentuck Knob

Kentuck Knob in Fayette County is the second Frank Lloyd Wright-designed home to make my list of the 7 man-made wonders of the PA Laurel Highlands, built in 1954 for Isaac and Bernardine Hagan, founders of the Hagan Ice Cream company in nearby Uniontown, PA.

The Hagan House at Kentuck Knob is an example of what Wright called a Usonian home, his concept of what an affordable American home for the masses should look like.

Construction characteristics of Usonian homes included using native materials, flat roofs with cantilevered overhangs, lots of natural lighting, and radiant floor heating.
