A bomb squad responded Sunday to reports that several Civil War era bombshells had been uncovered by Hurricane Matthew's erosion along the coast of Folly Beach, South Carolina.

The discovery was announced by the Charleston County Sheriff's Office on its Facebook page Sunday afternoon, along with a photo of the unexploded bombs. The shells were located by a man who was walking along the shoreline, according to WIS-TV, and technicians had to wait through high tide to examine the 12 to 15 ordnances that were discovered.

The area was blocked off to the public immediately after authorities were told about the bombs, according to the Post and Courier.

The City of Charleston announced via Twitter that it would detonate the shells Sunday night, and residents nearby may hear loud sounds as a result.

Folly Beach is located about 10 miles southwest of Fort Sumter National Monument – the site where the first shots of the Civil War were fired in 1861.
