Fort Mott State Park in Pennsville, New Jersey, is hosting a World War I living history event this weekend. It's been 100 years since the U.S. entered the war. 

More than 140,000 New Jerseyans served in the Great War. Many of them served stateside as part of the nation's coastal defense network. Fort Mott was established as one of three military fortresses to guard the Delaware River just after the Civil War but it remained operational through WWI. It was later acquired as both an historic landmark and idyllic park by the state in 1947.

To mark the 100th anniversary since the U.S. entered The Great War Fort Mott will stage a WWI-era re-enactment with unformed 'soldiers' showing how they were trained to defend the U.S. from a German attack. 

There will also be interactive displays and tours of the compound's fortifications.

Saturday, May 6 and Sunday, May 7, 10 a.m. to 3 p.m. - 454 Fort Mott Road, Pennsville, N.J.
