Preservationists are using high tech-methods to protect Civil War artillery at a fort in South Carolina that fired on Fort Sumter to open the Civil War 150 years ago.
The National Park Service has completed a project in which 10 massive cannons at Fort Moultrie on Charleston Harbor have been conserved with modern epoxy coatings and equipped with computer sensors.
The sensors are in the barrels of the cannon and provide readings on how temperature and humidity affect the massive iron guns that weigh more than 7 tons each.
The guns along with what the fort calls Battery Row are also now mounted on new concrete bases.
Moultrie was one of the forts surrounding Charleston Harbor from which Confederates fired at Union troops in Fort Sumter in April 1861.
