Police in Georgia are investigating an explosion Wednesday targeting the Georgia Guidestones monument, which the state says is known as “America’s Stonehenge.”

The early morning blast “destroyed a large portion of the structure” in northeastern Elbert County, according to the Georgia Bureau of Investigation.

“The preliminary information indicates that unknown individuals detonated an explosive device at around 4:00 a.m. on Wednesday, July 6th,” the agency said in a statement.

The Elbert County Sheriff’s Office is among the law enforcement agencies investigating and a bomb squad has been called to the scene, according to Fox5 Atlanta.

“Known as America’s Stonehenge, this 19-foot-high monument displays a 10-part message espousing the conservation of mankind and future generations in 12 languages,” according to a description on the state of Georgia’s tourism website.

The site is about 7 miles north of Elberton, near the South Carolina state line. Granite quarrying is a top local industry.

The roadside attraction received renewed attention during Georgia’s May 24 gubernatorial primary when third-place Republican candidate Kandiss Taylor claimed the guidestones are satanic and made demolishing them part of her platform.
