Sihanoukville, also known as Kampong Som, is located in southern Cambodia on the Gulf of Thailand, and is Cambodia's only international marine port. Its beaches are the most prominent natural feature of the city, spanning most of the surrounding coastline. Sihanoukville has several cultural sites, including Victory Monument built to symbolize friendship with Vietnam, and Independence Square, constructed in honor of independence and the Cambodians that lost their lives defending their country.
