South Carolina is a state that's blessed with seemingly endless natural beauty. From the mountains to the sea, the natural wonders in South Carolina are tried and true crowd-pleasers.

On the flipside, the Palmetto State is also home to some truly spectacular man-made wonders. Let's take a look at a few of them now.

1. Man-made Lake Jocassee was created when an incoming hydroelecteric facility aimed to flood several rivers.

Most buildings were demolished prior to the flooding. However in recent years divers discovered a Lodge, still intact, submerged in 300 feet of Lake Jocassee's crystal clear waters. Another diver found these signs in the lake.

2. Poinsett Bridge is the oldest bridge in South Carolina. It stretches 130 feet over Little Gap Creek in Greenville County.

The 14-foot arch in the Poinsett is a beautiful architectural detail of this charming bridge.

3. In 1793, work began on a major canal that would link Charleston and Columbia by way of water transportation. It was a nine-year project that involved creating a 22-mile canal.

The arrival of railroads in South Carolina eventually made the canal's main transportation function obsolete. Today, the Old Santee Canal is used mainly for recreation.

4. Fort Sumter - shown here on April 14, 1861 under the Confederate flag.

Construction of Fort Sumter began in the early 1800s after the end of the War of 1812. Seventy thousand tons of granite was imported from New England to build up the sandbar at the entrance to Charleston's harbor. Then an estimated seven million "charleston grey" bricks were handmade - reportedly by local plantation workers (slaves) - and hand laid. The original structure towered 50-feet over the low tide mark. The outer walls of Fort Sumter are five feet thick. Today, some of the fort has been "filled in" as you can see in comparisons of these two photos.

5. The chipping away of this upstate mountain to form Stumphouse Mountain Tunnel in the 1830s was halted after digging out only about one-third of the intended 1.1 mile tunnel. The purpose of the tunnel was to construct a more direct trade route from Charleston to the Ohio Valley.

Today, Stumphouse Tunnel is part of a park in the Town of Wahalla. The park also includes Issaqueena Falls.

6. Ravenel Bridge - Charleston and Mount Pleasant, SC.

The Ravenel Bridge connecting Charleston to Mount Pleasant is the third-longest cable-stayed bridge in the Western Hemisphere. It's also one of the most photographed landmarks in the Lowcountry.

7. Sea creatures are nurtured by this man-made reef 10 miles to the east of Little River Inlet.

That's right, this unique reef is made from repurposed out-of-commission Army personnel vehicles. The fish seem to like the new digs this man-made reef has provided.

8. The Hunting Island Light is a man-made natural wonder. Here's why...

The Hunting Island Light is what's called a "segmented cast iron" construction. It's designed to take apart in case the light ever needs to be moved. Each cast iron segment weighs approximately 1200 pounds. They're bolted together and then the inside and outside of the tower is lined with brick.

The light was constructed in the 1860s on the northern end of the island. By the late 1880s erosion on the northern end of Hunting Island forced a relocation of this man-made wonder to its present spot, a little over a mile from its original perch.
