CHARLESTON, S.C. (WCBD) – An item believed to be an old cannonball was safely removed from Fort Sumter over the weekend.

The fort, now a popular tourist destination that sits on an island in the middle of Charleston Harbor, was closed on Saturday after the ordnance was discovered, according to officials with Fort Sumter National Historic Park.

“Out of an abundance of caution the fort was closed and the last tour boat of the day was cancelled,” said park officials.

Emergency service divisions were called to the fort and an intact Civil War-era cannonball was safely removed following a full investigation.

There was no damage to historic structures at the fort, and no injuries were reported.

The fort resumed normal operations on Sunday. News 2 reached out to the fort for additional information.
