From the website:
The Great Cross of Christ stands 60 ft. tall on Dunbar's Knob, offering a breathtaking view, including the USX Tower in Pittsburgh on a clear day. Built in 1950 for the United Methodist Church, this inspiring landmark has touched the hearts of people from around the world. A paved walking path climbs through a beautiful wooded area, with benches along the way to rest. If this hike is too steep, you may contact the office during business hours to get a key to allow you to drive to the cross.
