The Plaza de España located in central Hagåtña, the capital of the United States territory of Guam, was the location of the Governors Palace during the island's long period of Spanish occupation. Most of the palace was destroyed during the shelling of Hagåtña during the reconquest of Guam in World War II. There are three structures still standing including the three-arch gate to Almacen (Arsenal), the azotea or back porch, and the Chocolate House. The plaza was listed on the National Register of Historic Places in 1974.
The Merlyn G. Cook School, also known as the Merizo School, is a historic former school building on GU 4 in Merizo, Guam. Built sometime before 1931, it is one of the first schools built during the administration of the island by the United States Navy. Its construction methods are transitional, including both traditional Chamorro-Spanish methods and period American methods. A series of concrete pillars provide the main structure, with the flooring substructure and wall framing of insect-resistant ifil wood. The windows are covered with rare ifil-wood shutters that pivot horizontally. The building's interior is clad in wood planking typical of early 20th-century Chamorro construction. The school has long served as a community meeting point, and was used as a place of refuge during World War II.
The Atantano Shrine is a historic commemorative marker near Piti, Guam. It is a pyramidal structure of coral limestone and concrete, about 2.5 metres (8.2 ft) in height, with base dimensions of 1.6 metres (5.2 ft). It is topped by a wooden cross and protected by an open concrete shelter. The monument was built in at least three stages, the early stages acting as bases for the mounting of the later ones. Panels on three sides carry inscriptions. The oldest inscription marks the initial construction of the road between Piti and Agat under the governorship of Don Felipe Cerain in 1784–85. The second inscription commemorates the creation of rice fields in the area under by Governor Don Francisco Villabos in 1832–34, and the third marks the reconstruction of the coast road during the governorship of Edward John Dorn in 1908–09. Commemorative markers of this type were a fixture of Spanish colonial administration that were adopted by Guamanians. The shrine has been the site of annual festivities since before World War II.
The Agana Historic District in Hagåtña, Guam is a 2-acre (0.81 ha) historic district that was listed on the U.S. National Register of Historic Places in 1985. It includes five contributing buildings: the Calvo-Torres, Rosario, Martinez-Notley, Lujan and Leon Guerrero houses. The area is roughly bounded by 2nd S., 3rd S., and 9th W., Santa Cruz and Legaspi Sts. in Agana.
The former Japanese Hospital building on the island of Rota in the Northern Mariana Islands is one of the few remaining Japanese-era buildings on the island. It is a single-story L-shaped concrete structure. When listed on the National Register of Historic Places in 1981, it was described as being in derelict condition, being little more than the concrete structure, lacking a roof, windows, and most of its woodwork. The window openings are sheltered by typical Japanese concrete canopies. The building was built by the Japanese about 1930, during the South Seas Mandate period; most Japanese-built structures on Rota were destroyed during World War II.
The Nan'yō Kōhatsu Kabushiki Kaisha complex was the main support base of the Nan'yō Kōhatsu Kabushiki Kaisha (NKKK) on the island Tinian in the Northern Mariana Islands. The NKKK was an economic development company established by the Empire of Japan to develop the territories of the South Seas Mandate, which it oversaw between the First and Second World Wars. In the Northern Marianas, the company aggressively developed arable areas for sugar cane farming, importing workers from Japan, Okinawa, and Korea. Each of the three major islands had major support facility. On Tinian, this area, now roughly where the island's largest community, San Jose is located on the south coast, consisted of an extensive development, most of which was destroyed during the Battle of Tinian in the Second World War. Of this large complex, only four buildings or structures remain, all of which have been listed on the United States National Register of Historic Places, as rare surviving examples of pre-war Japanese architecture on the islands.
The Rectory on the island of Rota in the Northern Mariana Islands is a rare example of transitional Spanish-Japanese architecture in the archipelago, now a United States commonwealth. It was built about 1930, during the South Seas Mandate period of Japanese administration, when the native Chamorro people were displaced to this area by workers imported by the Japanese to work in the sugar fields. The rectory is an L-shaped concrete structure measuring 13.7 by 19.8 metres, and originally had a wood-framed second floor and roof. Although only the concrete frame remains, elements such as its massive steps and window placement are typical of the earlier Spanish period, while decorative elements such as its porch columns and window opening details are distinctly Japanese.
The Nan'yō Kōhatsu Kabushiki Kaisha Sugar Mill is a former industrial facility in the village of Songsong on the island of Rota in the Northern Mariana Islands. Its ruins are a significant reminder of the South Seas Mandate period, when Imperial Japan engaged in large-scale sugar cane farming in the Northern Marianas, and are the only brick structure in the Northern Marianas. The sugar mill on Rota was one of the major installations of the Nan'yō Kōhatsu Kabushiki Kaisha, the Japanese company responsible for economic development of the mandate area. Its Executive Director turned Board Chairman. Haruji Matsue, considered the Northern Mariana Islands, the best place to establish the sugar industry, and more especially since previous Japanese commercial enterprises tried their hand at growing and processing sugar cane, but failed. The Nan'yō Kōhatsu Kabushiki Kaisha, was the most dominant economic force and being the largest Japanese Corporation, came to the Northern Marianas in 1921. Not unlike its predecessors, the NKK experienced a very tough few years, which almost forced the company to cease operations. Things started to take a turn for the better in 1926. By the early 1930s, Matsue proceeded to expand the company's landholdings and operations to Tinian and Rota, respectively. Rota had one mill and 38% of the farmlands had sugar cane growing. The remnants of this sugar mill, all that survived the Allied capture of Rota during World War II, are located on the north side of the peninsula that projects southwest from Songsong, and consist of fragments of brick and concrete structures. The most impressive single element is a brick and concrete tunnel 42.5 metres (139 ft) long, from which openings lead to the locations of other parts of the once-extensive complex.
The Agana-Hagåtña Pillbox is a former Japanese defensive fortification in Hagåtña, Guam. It is a six-sided reinforced concrete structure, located a short way above the high-tide line on the west side of the Paseo de Susana, a small peninsula jutting north from the village center. There is another wall providing cover for the entrance on the land side. The interior is divided into two chambers, each of which has a gun port. The structure was built by Guam's Japanese defenders during their occupation of the island (1941–44) in World War II.
The Faha Massacre Site is located just behind the Pigua cemetery in the village of Merizo on the United States island of Guam. The site is demarcated by four concrete pillars, connected by metal cables, with several crosses placed inside that area. A metal plaque mounted on a concrete block commemorates the thirty native Chamorro men who were slaughtered here on July 16, 1944, by members of the Imperial Japanese Army (IJA) during the Japanese occupation of the island during World War II. The IJA routinely forced Guam's native population to work on its construction projects. The men who were killed here were rounded up for a work crew; why they were killed is unclear, as there were no survivors. The massacre took place one day after the Tinta Massacre, and about one week before the liberation of the island began.
The Gongna Beach defenses are a collection of World War II structures built on or near Gongna Beach in Tamuning on the island of Guam, now a United States territory. These defenses were erected by the Imperial Japanese Army during its occupation of the island 1941–44. The three surviving elements were listed on the National Register of Historic Places in 1991. They are located well north of the main Allied landing areas of the 1944 Battle of Guam.
The Malessu' Pillbox is a World War II-era Japanese-built defensive fortification on the shore of Merizo, Guam. Located about 15 metres (49 ft) from the high-tide line at Merizo Beach, it is a rectangular structure built of steel-reinforced concrete and basalt rock. It is 3.9 metres (13 ft) deep, 2.4 metres (7.9 ft) wide, and about 2.42 metres (7.9 ft) high, although only about 0.75 metres (2.5 ft) of the structure is visible above ground. Its gun port has a view of the Merizo pier, and is approximately at ground level. It was built by Japanese defenders during their occupation of the island 1941–44.
The Mana Pillbox is an old World War II-era Japanese-built defensive fortification on the east coast of the island of Guam. It is located south of the village of Talofofo, about 50 metres (160 ft) inland from the point marking the south end of As Anite Cove. It is a structure built out of coral limestone and concrete, with an interior chamber about 3 by 1.8 metres in size. The entrance is on the south side, measuring 0.85 by 1.45 metres. There is one gun port, facing north, measuring 0.32 by .9 metres. The structure was designed to be well hidden in view from the sea and air. It was built, probably by conscripted Chamorro labor, during the Japanese occupation period 1941–44.
The Merizo Conbento is a historic building on Guam Route 4 in Merizo, Guam. Built in 1856, it is the oldest known occupied building on the island. It is a two-story concrete and ifil-wood structure with a gabled corrugated-metal roof, and a large set of concrete stairs leading to the main level above a raised basement. The present-day exterior is a faithful representation of the building's original appearance (with the exception of the roofing material, and original walls of manposteria remain inside the structure. It was built as a parish house for the local Roman Catholic diocese, and saw use as a military post and prison during the Japanese occupation period during World War II.
The Mount Tenjo Fortifications are a historic defensive gun battery site on Mount Tenjo, a hill overlooking Apra Harbor, the principal deep-water port on the island of Guam. The site includes concrete mounting pads for seven guns and the crumbling remains of a concrete command post structure. These facilities are located just below the crest of the hill on its west side. A defensive trench also extends along the top of the plateau-like hill. Unlike most early 20th-century fortifications on Guam, these facilities were built in the late 1910s by the United States Navy, and not by Japanese forces during the World War II occupation period. These are the only known surviving pre-World War II defensive fortification sites on the island. They were functionally abandoned as a result of the 1922 Washington Naval Conference. Mount Tenjo was the site of battle during the 1944 liberation of Guam.
The San Vitores Beach Japanese Fortification are the remains of World War II-era defensive positions facing the beach of Tumon Bay on the west side of the island of Guam. Located near the stairs to the beach of the Guam Reef Hotel are the remains of two concrete pillboxes built by Japanese defenders during the occupation period 1941–44. One structure, of which little more than a gun embrasure is discernible, is located in the limestone cliff about 10 metres (33 ft) inland from the high tide line, and a second is located about 10 meters south and 8 meters further inland, with only a section of roof slab and supporting columns recognizable.
The Talofofo Pillbox is a historic World War II-era defensive fortification in Talofofo, Guam. It is located near the coast, about 127 metres (417 ft) south of the mouth of the Togcha River and 27 metres (89 ft) inland from the high-tide line. It is roughly 2.75 by 3.0 metres, built out of concrete and coral limestone. Its walls are about 0.5 metres (1.6 ft) thick, with an embrasure providing a view of the Togcha River, and a window looking over the coast to the east. Its entrance is on the landward (south) side. This structure was built under the direction of the Imperial Japanese Army during its occupation of Guam in 1941–44.
The Tokcha' Pillbox is a Japanese-built World War II-era defensive fortification on the island of Guam. It is built on a limestone terrace on Togcha Point, about 1 mile (1.6 km) north of the Togcha River and 0.7 miles (1.1 km) south of the Ylig River. It is set in a depression excavated from the limestone about 15 metres (49 ft) inland from the high tide land and 1 metre (3.3 ft) above sea level. It is a roughly rectangular structure built out of steel-reinforced concrete filled with coral and beach aggregate. The entrance is on the north wall, sheltered by a wall of coral blocks, and the gun port is on the south wall. This structure was built under the direction of the Japanese military during their occupation of the island 1941–44.
The Tumon Bay Japanese fortifications are a collection of World War II-era military structures along the coast of Guam in and near the village of Tumon. Many of these structures were listed on the National Register of Historic Places in 1991, using the alternate spelling "Tomhum". They include pillboxes on or close to the beach, and concrete structures and caves located a short way inland on the limestone cliffs that overlook the beach.
The Richards, Dexter, & Sons Woolen Mill, also known locally as the Dexter Mill, is a historic industrial property at 169 Sunapee Street in Newport, New Hampshire. Built in 1905, it is a well-preserved example of period mill architecture, which served as an important area employer for many years. The property was listed on the National Register of Historic Places in 1985.
