Piti Guns: Silent Sentinels of Guam's WWII History

Piti Guns, located in the War in the Pacific National Historical Park, offers a glimpse into Guam's pivotal role during World War II. The site features three Vickers-type Model 3 140-millimeter coastal defense guns manufactured by the Japanese in 1914. These guns were strategically positioned in Piti in 1944 to defend Asan Beach and Apra Harbor from potential U.S. invasion. With a firing range of nearly 10 miles, they were intended to target ships and landing craft.During the Japanese occupation from 1941 to 1944, the local Chamorro population was forced to construct these defensive positions, hauling thousands of pounds of steel up the steep terrain. Despite the extensive effort, the guns were never fully operational and remained silent when U.S. forces landed on July 21, 1944, to retake Guam. Today, the guns serve as a representation of the weaponry used by the Japanese for fortification efforts in Guam.The site is accessible via a short but steep trail, about 1/4 mile long, that begins in Piti. The trail winds through a lush coastal jungle, offering a sense of the challenging conditions faced by soldiers during the war. The area also features a mahogany forest, planted around 1928 as part of an agricultural experiment station. From the Piti Guns site, visitors can enjoy views of Apra Harbor and the surrounding coastline.
