KTWG (801 AM) is a radio station broadcasting a religious radio format. Licensed to Hagåtña, Guam, United States, it serves Guam and Marianas Islands. The station is currently owned by Edward H. Poppe, Jr. and Frances W. Poppe, and is managed by Leilani Dahilig. The station's studios are located in Piti. While the station broadcasts at 801 kHz, many American radios, especially the digital readout variety, were capable of tuning in AM stations in 10 kHz increments only. Therefore, in the station's marketing, the nearest frequency, "800", is used instead. Stations in Guam fall within the jurisdiction of the Geneva Frequency Plan of 1975, instead of the North American Regional Broadcasting Agreement, whose coverage includes the U.S. mainland. KTWG is the primary entry point for the Emergency Alert System in Guam and the Northern Mariana Islands.

Piti is a village located on the central west coast of the United States territory of Guam. It contains northern and eastern coastlines of Apra Harbor, including Cabras Island, which has the commercial Port of Guam and the island's largest power plants. Piti was a pre-Spanish CHamoru village and, after Spanish colonization, became the primary port town on Guam. The town was largely destroyed during the 1944 liberation of Guam and the population relocated during the wartime construction of Apra Harbor.

The Piti Guns or Piti Coastal Defense Guns is the site of three Vickers-type Model 3 140-millimetre (5.5 in) coastal defense guns in the War in the Pacific National Historical Park in Piti, Guam. The Japanese manufactured these Model 3 coastal defense guns in 1914. During the Japanese Occupation of Guam from 1941 to 1944, they built up defensive positions on the island. 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. This area was chosen to defend the beach at Asan from a possible invasion. 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. Consequently, not one of the three coastal defense guns was ever fired. However, these guns are representative of the type of weapons used by the Japanese on Guam for fortification efforts.

The Quan Outdoor Oven is a 20th-century version of a traditional hotnu, or outside oven, on the island of Guam. This oven is located on Quan family land on J. C. Santos Road, south of Santos Memorial Park in Piti. Although built out of modern materials, it follows a traditional form that has been in use on Guam since these ovens were introduced by the Spanish in the 17th century. It is a barrel-shaped structure about 2 metres (6.6 ft) long, 1.68 metres (5.5 ft) wide, and 1.37 metres (4.5 ft) wide, rising to a height of 0.64 metres (2.1 ft). The base of the structure is either poured concrete or concrete blocks. The interior of the vault is made out of heat-resistant bricks, while the exterior is finished in concrete. When recorded in 2010, its main opening was damaged. The oven was listed on the National Register of Historic Places in 2010.

The Matgue River Valley Battle Area was the site of a decisive Allied victory during the 1944 Battle of Guam. The area was the scene of a major counterattack by Japanese forces against the Allied beachhead, in which the Japanese suffered extremely heavy casualties and were beaten back. After this attack, the remaining Japanese forces on the island retreated to the north. The area is located in the hills southwest of Asan Point along the Matgue River. The only surviving structural remnants associated with the battle are caves dug by the Japanese as defensive positions prior to the invasion. The site was listed on the National Register of Historic Places in 1975.

The Capture of Guam was a bloodless engagement between the United States and Spain during the Spanish–American War. The U.S. Navy sent a single cruiser, USS Charleston, to capture the island of Guam, which was under Spanish control. The Spanish garrison on the island had no knowledge of the war and no real ability to resist the American forces. They surrendered without resistance, and the island passed into American control. The event was the only conflict of the Spanish–American War on Guam.

The Fonte River Dam is a historic dam on the Fonte River on the island of Guam. It is located in the upper third of the river's main valley, which is located between Nimitz Hill Annex and Agana Heights, and lies below and west of the Libugon scenic overlook on Nimitz Hill. The dam, built in 1910, was part of the first organized effort by the United States Navy to provide a reliable water supply to the island's major settlement, Hagåtña (formerly Agana). It is a concrete structure 150 feet (46 m) long, 24 feet (7.3 m) high, and has a 17 feet (5.2 m) base. It is almost complete obscured by jungle overgrowth. The dam was listed on the National Register of Historic Places in 2014.

Korean Air Flight 801 (KE801, KAL801) was a scheduled international passenger flight operated by Korean Air, from Gimpo International Airport, Seoul to Antonio B. Won Pat International Airport, Guam. On August 6, 1997, the Boeing 747-300 operating the flight crashed on Bijia Peak, south of Nimitz Hill, in Asan-Maina, Guam, while on approach to the destination airport, killing 229 of the 254 people aboard. The National Transportation Safety Board cites poor communication between the flight crew as the probable cause of this accident, along with the captain's poor decision-making on the non-precision approach.
