Sullivan's Island Range Lights

Battery Jasper is a military extension of Fort Moultrie. Built in 1897, it housed multiple weapons due to its proximity to Charleston Harbor. It has a powerhouse that was built in 1910 to power the fort. Only a quarter of the structure is open to the public because the rest was deemed unstable. It was named after William Jasper who was best known for rescuing a shot down South Carolina flag at the same location. It is of the same style as Battery Thomson and was built close to the same time as Battery Gadsden.

The Battle of Sullivan's Island or the Battle of Fort Sullivan was fought on June 28, 1776, during the American Revolutionary War. It took place near Charleston, South Carolina, during the first British attempt to capture the city from American forces. It is also sometimes referred to as the first siege of Charleston, owing to a more successful British siege in 1780. The British organized an expedition in early 1776 for operations in the rebellious southern colonies of North America. Delayed by logistical concerns and bad weather, the expedition reached the coast of North Carolina in May 1776. Finding conditions unsuitable for their operations, General Henry Clinton and Admiral Sir Peter Parker decided instead to act against Charlestown. Arriving there in early June, troops were landed on Long Island (now called Isle of Palms), near Sullivan's Island where Colonel William Moultrie commanded a partially constructed fort, in preparation for a naval bombardment and land assault. General Charles Lee, commanding the southern Continental theater of the war, would provide supervision. The land assault was frustrated when the channel between the two islands was found to be too deep to wade, and the American defenses prevented an amphibious landing. The naval bombardment had little effect due to the sandy soil and the spongy nature of the fort's palmetto log construction. Careful fire by the defenders wrought significant damage on the British fleet, which withdrew after an entire day's bombardment. The British withdrew their expedition force to New York, and did not return to South Carolina until 1780.

Fort Moultrie is a series of fortifications on Sullivan's Island, South Carolina, built to protect the city of Charleston, South Carolina. The first fort, formerly named Fort Sullivan, built of palmetto logs, inspired the flag and nickname of South Carolina, as "The Palmetto State". The fort was renamed for the U.S. patriot commander in the Battle of Sullivan's Island, General William Moultrie. During British occupation, in 1780–1782, the fort was known as Fort Arbuthnot.

Charleston Light, also known as Sullivan's Island Lighthouse, is located on Sullivan's Island, South Carolina, which is the northern entrance to Charleston Harbor. Designed by Thomas Sullivan. The lighthouse was erected to replace the defunct Morris Island Light on Morris Island, which was at risk of being destroyed by erosion, but which remains standing and was stabilized in 2010. Construction of the Charleston Light was started in 1960, and it was first lit on June 15, 1962.Charleston Light has a steel frame, an aluminum alloy skin, and a triangular cross section. It is 140 feet (43 m) tall. Its slim, triangular structure was built to withstand winds of 125 miles per hour, and the focal plane of the light is 163 feet (50 m) above mean sea level. Originally, it was painted white and red-orange, but was later repainted white and black after citizens complained about the distracting color of the upper half. It is the only U.S. lighthouse with an elevator and air conditioning, and was the last onshore manned lighthouse to be built by the Federal Government. The Texas Tower Offshore Lighthouses were the last offshore manned lighthouses and, were built later starting in 1961 with Buzzards Bay Entrance Light.It has a DCB 24 light. It originally had 28 million candelas (candlepower) and was the second most powerful in the Western Hemisphere. As the light was actually too dazzling, the power was lowered to 1.2 million candelas and could still be seen over 26 nautical miles (48 km; 30 mi). Its characteristic is two 0.2 s flashes separated by 4.8 s every 30 s. The light was automated in 1975.It is a non-contributing resource located in the U.S. Coast Guard Historic District. Now part of Fort Sumter and Fort Moultrie National Historical Park. Although it was donated by the Coast Guard to the National Park System in 2007, the Coast Guard continues to maintain the light of the lighthouse, while the National Park System protects its historical significance and overall physical upkeep.Although this lighthouse is still a working light, many problems within its structure keep it from being open to the public. Currently it is fenced off from civilians, but visitors are able to explore the surrounding grounds, as well as the adjacent public beach access, in order to view the lighthouse.

Sullivan's Island, historically known as O'Sullivan's Island, is a town and island in Charleston County, South Carolina, United States, at the entrance to Charleston Harbor, with a population of 1,791 at the 2010 census, and 1,891 people in 2020. The town is part of the Charleston metropolitan area, and is considered a very affluent suburb of Charleston. Sullivan's Island was the point of entry for approximately 40 to 50 percent of the 400,000 enslaved Africans brought to Colonial America, meaning that 99% of all African Americans have ancestors that came through the island. It has been likened to Ellis Island, the 19th-century reception point for immigrants in New York City. During the American Revolution, the island was the site of a major battle at Fort Sullivan on June 28, 1776, since renamed Fort Moultrie in honor of the American commander at the battle. On September 23, 1989, Hurricane Hugo came ashore near Sullivan's Island; few people were prepared for the destruction that followed in its wake. The eye of the hurricane passed directly over Sullivan's Island. The Ben Sawyer Bridge was a casualty, breaking free of its locks. Before the storm was over, one end of the bridge was in the water and the other was pointing skyward. Sullivan's Island police chief, Jack Lilien, was the last person to leave the island before the bridge gave way.

The Ben Sawyer Bridge is a swing bridge that connects the town of Mount Pleasant with Sullivan's Island in South Carolina. The bridge swings on its central axis to open for boat traffic which is too tall to clear the bridge, and has an operator's house in the center of the swing span from which a tender can operate the bridge. The bridge was originally constructed in 1945, but the steel superstructure for the approach spans and swing span was replaced in 2010, albeit retaining the same general appearance. The bridge originally cost about $775,000 (substructure, superstructure, and approaches) for the 247 foot span (total 1,154 length) with a 32 foot clearance (at high tide). The bridge is approached on both sides by a causeway; applications for the dredging were filed in July 1941. The contractor was to dig a 50 foot wide channel through the mud which would then be filled with dredged sand from the nearby waters. Although the preliminary work moved forward, progress on the superstructure of the bridge was held up for many months due to the lack of steel during World War II; the military supported the completion of the project, though, and the project moved forward again starting in 1943. The bridge opened to traffic on June 18, 1945. Prior to completion of the Isle of Palms Connector Bridge in 1993, the Ben Sawyer Bridge provided the only vehicular access to Sullivan's Island, and, by a connecting bridge, Isle of Palms.The bridge was heavily damaged during Hurricane Hugo, leaving one end of the main span in the Intracoastal Waterway. Pictures of the damaged bridge are some of the most recognizable lasting images of the destruction wrought by the storm. It was subsequently repaired and reopened to traffic in October 1989.
