Discover more about Piti Guns

Nestled in the hills above Piti village, the Piti Guns offer a glimpse into Guam's pivotal role in World War II. These three Vickers-type Model 3 140mm coastal defense guns were installed by the Japanese in 1944 as part of their efforts to fortify the island against American forces. The Chamorro people were forced to work in building up these defenses. The guns were intended to protect Apra Harbor and Asan Beach from approaching ships and landing craft. Each gun weighed over 12,000 pounds and had a range of approximately 10 miles.Strategically placed in a former rice paddy village, the guns were never fully operational when U.S. troops landed on July 21, 1944, and were never fired. Today, they remain in their original emplacements, offering a tangible connection to the past. Visitors can explore the site via a short but steep trail, immersing themselves in the dense coastal jungle reminiscent of the conditions faced by soldiers during the war.The surrounding mahogany forest, planted in 1928 as part of an agricultural experiment station, adds to the site's unique atmosphere. The Piti Guns serve as a poignant reminder of the sacrifices and struggles endured during the war, and the resilience of the island and its people.
