The Shute's Folly Beacon sheds light on activities that occur on Shute's Folly, the small island in Charleston Harbor where Castle Pinckney is located. This section takes its name from the beacon that was set up on a tower at Castle Pinckney in 1855 (shown at left in masthead above). The abandoned fort served as a lighthouse station and depot until 1917.*

Coastal birds, including Eastern Brown Pelicans and American Oystercatchers, call Shute's Folly home during the nesting season. Between nesting seasons, Castle Guardians volunteer regularly to visit the brick-and-mortar fort to protect and maintain the site. They often perform other tasks, including flag-raising ceremonies, to recognize historic flags and events, and to honor causes.

An archaeologist's trowel, like the one shown immediately above, will designate archaeological reports.

Apr. 25, 2026:  Castle Guardians Conduct "Another General Maintenance Workday" at Castle Pinckney

Charleston, S.C. ─ Castle Guardians, taking advantage of good weather, conducted “another general maintenance workday" at Castle Pinckney on Shute's Folly in Charleston Harbor on Saturday, April 25.

“Our objective was to cut weeds and to cut up the remains of several Palmetto trees we cut down earlier in the spring for burning, and we accomplished most of it in just a few hours before the weather deteriorated, and we were forced to leave," said Matthew Locke, who regularly leads Castle Guardians -- volunteers all -- to maintain the fort when coastal birds are not nesting there. “We cut back and trimmed almost all of the overgrowth inside the fort, cut up into small sections all of the felled Palmetto trees and cut down and removed one more tree.  More

*More on the Beacon at Castle Pinckney -- A yellow tower, which included a beacon, was constructed at Castle Pinckney in 1855 prior to the War Between the States. The beacon had a 5th order, non-rotating Fresnel lens and a focal plane of 50 feet that permitted its light to be visible at a great distance. The masthead at the top of this page, showing the tower with its beacon at left, was produced from the engraving published in 1861 by Harper's Weekly shortly after the war began See engraving, “Castle Pinckney: Silent Sentinel ...". In the 1866 chart at the bottom of this page, the beacon is also identified next to Castle Pinckney on Shute's Folly.

Castle Pinckney was transferred to the Lighthouse Board in 1878 for use as a lighthouse depot for the Sixth District, serving lighthouses from North Carolina to Florida. A lighthouse, built at Castle Pinckney in 1880, replaced the original tower and its beacon. The newer lighthouse was built in 1890 when the fort became a lighthouse station. A lighthouse depot was situated on Tradd Street in Charleston in 1916, and the lighthouse station at Castle Pinckney was deactivated in 1917.
