For as long as most people on Sullivan's Island can remember, the hill behind Stith Park was a place kids raided the recycling bin for. Flatten a cardboard box, haul it to the top of the grassy rise next to Town Hall, and ride it down the slope that generations of islanders simply call the Mound. The hill is what's left of Battery Capron, a mortar battery built in 1898 and handed over to the town decades ago once the Army had no more use for it. It eroded. The town patched it. Bamboo grew in. Kids kept sliding.
This summer, something else went up there.
What Actually Went Up There
The structure is a 60-foot slice of a palmetto log fort, standing 20 feet tall with two gun bays and a pair of replica cannons crowning the parapet, built by a Charleston-area SC250 commission to mark the 250th anniversary of the Battle of Sullivan's Island. Truluck Marine Construction, a company that normally builds docks, took the job on a compressed timeline that started in earnest on June 1 and had to finish before Carolina Day on June 28. General manager Rawlins Lowndes joked to a Post and Courier reporter that his crew wouldn't give up, that they'd be ready for the attack.
Sourcing the logs turned into its own small scramble. A few dozen came from Sullivan's Island itself, leftovers from Dominion Energy powerline clearing in 2024. That wasn't nearly enough to reach 20 feet, so Johns Island-based Sunnyside Farms donated the rest, palmetto trees cleared from properties on Kiawah and Seabrook Islands and stockpiled for no particular reason until owner Hank Walpole figured someone would eventually need them.
The fort is fenced so no one climbs it, but educational panels along the perimeter explain what the original 1776 structure did: absorb British cannonballs into spongy palmetto wood and sand rather than shatter under them, buying Colonel William Moultrie's outnumbered garrison enough time to turn back the Royal Navy in a battle that predates the Declaration of Independence by a week.
The Vote Nobody Was Neutral About
Getting the replica onto town land wasn't a formality. SC250 first hoped to rebuild on National Park Service ground at Fort Moultrie, the way the 1976 Bicentennial version had been done, but ground-disturbance restrictions ruled that out. Battery Gadsden came up as an alternate site before the Mound won out.
Town Council voted 6-1 on February 17, 2026, to authorize the project. The dissenting vote came from Councilmember Melanie Burkhold. One resident who spoke against the plan at the February meeting asked why the island's existing national park and visitor center weren't good enough, and worried the project would invite more visitors to an island that already has a beach and a dinner reservation to offer them.
Supporters framed it differently. Councilmember Justin Novak called it a chance for people to see the island as more than a place to grab dinner and hit the sand, to understand it in the context of the country's founding. Councilmember Ned Higgins said the island's residents are guardians of that history and that a little extra traffic was a fair trade. Mayor Patrick O'Neil put it simply: the town was celebrating something significant to the island, the state, and the country, and that was worth being proud of.
What $20,600 Actually Bought
Here's the detail that got buried under all the anniversary language. SC250 covered the entire cost of building, maintaining, and eventually removing the fort itself. The town's own contribution was a separate line item, roughly $20,600, and it didn't go toward logs or cannons at all. It paid for two new ADA-compliant parking spaces at the Mound, low-voltage lighting for nighttime visibility, gravel walkways, and security cameras.
Town Administrator Joe Henderson was blunt about why that mattered beyond the anniversary. Running electrical conduit to the top of the Mound, he said, would let events take place up there going forward. He called it money well spent, and he wasn't talking about the fort.
That distinction is worth sitting with. The fort is a guest. SC250 is contractually on the hook to dismantle and remove the entire structure once its run ends. The conduit, the lighting, the ADA access, the cameras: those stay. The town spent public money on infrastructure for a hill that has never had any, and the anniversary exhibit is just the reason it finally happened.
There was also a real engineering question buried in this, given the Mound's history of erosion problems and its earlier reputation as a slide surface rather than a load-bearing site. A geotechnical analysis by Terracon found the hill could support the fort's footings, but only after undercutting three feet of soil and replacing it with geogrid-reinforced compacted aggregate. The deck itself was designed to be semi-pervious rather than solid concrete, so stormwater drains through it instead of pooling the way it has on other parts of the Mound for years.
How to Actually See It Now
Carolina Day weekend brought an estimated 10,000 visitors to the island, a two-line shuttle system running to keep cars off the causeway, streets closed, the whole apparatus of a once-in-a-generation anniversary. That's not what a visit looks like now.
The exhibit runs as a self-guided experience with posted hours of 8:00 a.m. to 5:00 p.m. Parking is available along Middle Street and at Battery Thomson, behind the Sullivan's Island Post Office. Access to the top is pedestrian only, with a gate-controlled system for the two ADA spaces. There's no admission and no staff on site, just the fort, the panels, and whatever quiet a Tuesday afternoon in September offers compared to a June weekend that closed with the Royal Air Force Red Arrows performing overhead.
What Happens When the Fort Comes Down
SC250 president Brett Bennett told council the extended timeline, keeping the exhibit up through September 2027, was meant to give residents and visitors real time with it rather than a single weekend's worth. That's roughly 15 months from completion, long enough for the fort to become part of ordinary island life before it disappears again.
When it does come down, SC250 is responsible for the full removal at its own expense. What the town keeps is the part nobody photographed for the anniversary: a hill with power run to the top, real lighting, accessible parking, and security infrastructure it didn't have before. The same slope where kids once rode cardboard down the grass is now wired for whatever the island decides to do with it next, whether that's a concert, a gathering, or simply better light on an evening walk up to see the harbor.
The fort is temporary. The reason it's there long enough to matter, and what it leaves behind when it's gone, is the part of this story that doesn't end when Carolina Day does.
If you're already living this rhythm of island life and want more of what's actually changing around Sullivan's Island, or if a question about property on the island ever comes up, Crown Coast keeps a close eye on both.
