The Hotel Cambodiana (Khmer: សណ្ឋាគារខេមបូឌីយ៉ាណា) is a 239-room hotel on the banks of the Tonlé Sap River in the heart of Phnom Penh, Cambodia, approximately 10 km from Phnom Penh International Airport.Construction of the Cambodiana was initiated by Prince Norodom Sihanouk in the early 1960s. He originally requested a 10-bungalow luxury resort/government guesthouse, but noted Cambodian architect Lu Ban Hap suggested a larger international luxury hotel would be more profitable. Lu designed the structure in the then-popular New Khmer style. Construction of the Cambodiana began in 1963, on stilts on reclaimed land. The hotel opened in 1969, with 100 rooms, but only operated for a year. In 1970, Lon Nol's troops overthrew Prince Sianhouk and converted the hotel to military barracks. The hotel was abandoned during the Khmer Rouge period, later serving as refugee housing. In the late 1980s, a Singapore-based company purchased a 70-year lease from the Cambodian government. They restored and expanded the Cambodiana to 239 rooms, and reopened it in July 1990. The hotel was operated by the French Sofitel chain from 1992 to April 1, 2001 as the Sofitel Cambodiana. It was purchased by The Royal Group in 2005. In 2016, plans were announced to demolish the building and construct a 20-story replacement. In 2019 new plans were announced to replace the hotel with a 600-meter skyscraper.

The Cambodia–Vietnam Friendship Monument in Phnom Penh, capital of Cambodia, is a large concrete monument commemorating the former alliance between Vietnam and Cambodia. It was built in the late 1970s by the communist regime that took power after the Cambodian-Vietnamese War, which overthrew the Khmer Rouge regime. The monument is located at the Botum Park near the centre of Phnom Penh not far from the Royal Palace. It features heroic statues of Vietnamese and Cambodian soldiers in the "Socialist realist" style developed in the Soviet Union in the 1930s, together with images of a woman and baby representing Cambodian civilians. The monument is in a popular park in the middle of the city. The monument has occasionally become a political focal point. On August 30, 1998, during post-electoral protests, several people climbed onto the monument with hammers, poured gasoline on it and set it on fire. This damage was repaired two months later by the authorities. On July 29, 2007, a bomb exploded at the base of the monument, causing little damage.

The Khmer Republic (Khmer: សាធារណរដ្ឋខ្មែរ, Sathéarônârôdth Khmêr; French: République khmère) was a Cambodian state under the United States-backed military dictatorship of Marshal Lon Nol from 1970 to 1975. Its establishment was formally declared on 9 October 1970, following the 18 March 1970 coup d'état which saw the overthrow of Norodom Sihanouk's government and the abolition of the Cambodian monarchy. The main cause of the coup was Norodom Sihanouk's tolerance of North Vietnamese military activity within Cambodia's borders; Vietnamese communist forces had gained de facto control over vast areas of eastern Cambodia as a result. Another important factor was the dire state of the Cambodian economy, an indirect result of Sihanouk's policies of pursuing neutrality. With the removal of Sihanouk, the existing Kingdom of Cambodia became a republic, officially removing Sisowath Kossamak. The character of the new regime was far-right and militaristic; most significantly, it ended Sihanouk's period of covert co-operation with the North Vietnamese regime and the Viet Cong, and aligned Cambodia with South Vietnam in the ongoing Second Indochina War. The Khmer Republic was opposed within the Cambodian borders by the National United Front of Kampuchea (Front uni national de Kampuchéa, FUNK), a relatively broad alliance between Sihanouk, his supporters, and the Communist Party of Kampuchea. The insurgency itself was conducted by the CPNLAF, the Cambodian People's National Liberation Armed Forces: they were backed by both the People's Army of Vietnam (PAVN) and the National Liberation Front (NLF, better known as the Viet Cong), who occupied parts of Cambodia as part of their ongoing war with the South Vietnamese government. Despite the large quantities of military and financial aid from the United States, the Khmer National Armed Forces (Forces armées nationales khmères, or FANK) were poorly trained and unable to defeat either the CPNLAF or the Vietnamese forces of the PAVN and NLF. The Republic eventually fell on 17 April 1975, when the Khmer Rouge took Phnom Penh and briefly restored the Kingdom of Cambodia before renaming itself Democratic Kampuchea on 5 January 1976.

The Vann Molyvann House is a major landmark of the city of Phnom Penh built in 1966 by Khmer architect Vann Molyvann as his private house and architecture office. It has been dubbed as the "Cambodian Taliesin" and praised as a "testimony to the unique ability of Southeast Asia's greatest living architect to fuse European modernism with traditional Khmer design in an apparently seamless style."

The Chaktomuk Conference Hall (Khmer: សាលសន្និសីទចតុមុខ, Sal Sânnĭsit Châtŏmŭkh) is a theatre located in the city of Phnom Penh, Cambodia. The fan-shaped hall is one of the most iconic works of famous Cambodian architect Vann Molyvann. Mainly used for the purpose of conducting ceremonies for foreign governors, the hall is a designed concrete structure which radiates in a fan shape referencing a palm leaf. The design combines traditional building elements (Khmer architecture) with a modern structure. Most of the events that take place in the hall are performance art and meetings of high class like royalties and presidents.

The White Building, originally known as the Municipal Apartments, was a large and prominent apartment building in Phnom Penh, Cambodia, one of the buildings in the Bassac development. The White Building was on Samdach Sothearos Boulevard near the Bassac River, a large urban extension project built on reclaimed land in the early 1960s. The UN consultants Gérald Hanning and Vladimir Bodiansky introduced the concept of the building, a 450-metre (1,480 ft) architectural composition, directly inspired by previous AT.BAT designs built in Morocco. Lu Ban Hap, then Chief Architect of the Municipality of Phnom Penh, was responsible for the site supervision. The White Building was designed to house moderate-income tenants, and was adopted by many artists who found the innovative design appealing. With the nearby Grey Building, designed by Vann Molyvann, it was initially built for athletes in the 1964 GANEFO (Games of the non-aligned forces) international sports event. After years of neglect and deterioration since the fall of the Khmer Rouge, the White Building was demolished in 2017. The building was composed of six blocks of concrete construction, three or four stories tall, connected by open bridge structures, along a double-loaded spine. It included stores and doctors' offices as well as 468 apartments.Tenants fled during the Cambodian genocide in the 1970s. After the defeat of the Khmer Rouge in 1979 the White Building was reoccupied by former tenants and squatters. It gradually declined and became known for poverty, drug use and prostitution. Its population in 2015 was about 2500.According to municipal authorities, the building was structurally deteriorating and unsafe. Tenants used the high-ceilinged rooms to add lofts, and balconies were enclosed, obscuring the once-white building's design and also adding weight to the structure. Cracking appeared in 2015 after construction on an adjoining lot. Several proposals have been made to tear it down for redevelopment. Eviction orders were issued in July 2015. However, the building's status as an iconic New Khmer building stimulated preservation efforts.In July 2017, the almost 500 families still living in the White Building were moving out; the building was to be replaced by a 21-storey mixed-use development.
