The Chamorro population was forced to work in building up these defenses, and did so here at the Piti Guns.

The Piti guns were strategically placed in a village consisting mostly of rice paddies in 1944.

These guns have a firing range of close to 10 miles (16 km) and were intended for use against ships and landing craft.

When the United States Armed Forces came to retake the island on July 21, 1944, these guns were not fully operational.

The trailhead is located at 13.4621N, 144.6942E in a residential neighborhood behind a church social hall on Father Mel Street in Piti, Guam.
