An artillery shell from the Civil War was discovered in downtown Charleston this week.

Charleston Police Department tweeted Wednesday that the shell was found by a construction crew at Gillian Street, which is in the heart in the historic city. Roads were closed in the area while a U.S. Air Force Explosive Ordnance Disposal team removed the shell.

A spokesman for the Charleston Police Department confirmed to Fox News that the shell was subsequently destroyed by the Air Force EOD team.

HURRICANE DORIAN UNEARTHS CIVIL WAR CANNONBALLS ON SOUTH CAROLINA BEACH

An important Confederate port during the Civil War, Charleston withstood a long siege by Union forces until its surrender on Feb. 18, 1865.

Other Civil War ordinance has been discovered in the Palmetto State in recent years. Last year, for example, two Civil War cannonballs were uncovered on a South Carolina beach in the aftermath of Hurricane Dorian. The cannonballs were found on Folly Beach, which is located on Folly Island, a barrier island near Charleston.

Civil War sites and artifacts from the era regularly offer fresh glimpses into the bloody conflict. A Civil War-era gravestone linked to the infamous Quantrill’s Raid, for example, was discovered last year in a Kansas forest.

In 2018, the remains of two Civil War soldiers were discovered in a surgeon’s burial pit at Manassas National Battlefield Park in Virginia. Also in 2018, a vacationer on a North Carolina beach captured drone footage of Civil War-era shipwreck.
