As the newest Cambodian city, Sihanoukville doesn't have a long history like Phnom Penh or Siem Reap. It was founded in 1960 after independence from France as a port, in order to communicate the city with international trade. The project was overseen by the government of Norodom Sihanouk.
It is a province in southern Cambodia on the Gulf of Thailand. This port city is a growing Cambodian urban center, located 185 kilometres (115 mi) southwest of the Cambodian capital, Phnom Penh. The province is named after King Father Norodom Sihanouk and grew up around the construction of Sihanoukville Port. Construction on the port began in June 1955 and it was the only deep water port in Cambodia.The port was built in part due to the waning power of the French leading to the Vietnamese tightening their control over the Mekong Delta and hence restricting river access to Cambodia. Sihanoukville's beaches have made it a popular tourist destination.
