First Natural Bridge Under Heaven

    First Natural Bridge Under Heaven, or "Bridge Across the Sky" as it is formally known, is a natural bridge, i.e., a large sandstone block that has had a large, vertically elliptical section hollowed out of it near the summit, leaving a "bridge" at the top connecting the two pieces. One of the sides is a massive block while the other side is a nearly complete freestanding obelisk, except that it is still connected to the massive block at the base and at the top. The "bridge" at the top spans 25 meters in length, is 2 meters wide and is about 5 meters thick. First Natural Bridge under Heaven even holds a world record: it is the highest natural "bridge" in the world.
