During the last years of World War I, a new explosive was invented to help stretch the depleting stores of TNT. It was called Amatol, and in 1918, shortly after the United States entered the war, a munitions plant and adjacent factory town were established in New Jersey named after the explosive they manufactured.
Amatol, New Jersey, was built on 6,000 acres of land in the Pine Barrens. The planned community was short lived: After World War I ended that same year, Amatol became a vacant town. The homes were deserted and the plant shut down. Because most of the buildings were built to be temporary, they were dismantled and little was left behind. The factory was eventually demolished.
The structures that were left behind were made out of concrete, and if you make the hike out into the woods and look closely you can see the remnants of the former munitions village: piles of concrete that were once houses and concrete foundations where structures once stood.
You can also see hints of the racetrack that was built in 1926 on the site of the former munitions plant. The Amatol Racetrack, also known as the Atlantic City Speedway, was the biggest raceway on the East Coast at the time. Made out of wood, it was a 1.5-mile oval track, about 50 feet wide. You can still see the oval outline of the old speedway via Google Earth (coordinates: 39°36’4.59”N, 74°44’37.10”W), an eerie glimpse of where the raceway once existed.
