Phnom Penh is the capital of Cambodia and is rich in history, culture and natural beauty. The city is famous for its splendid royal palace, ancient monasteries and the beautiful Tonle Sap Lake. Visitors can explore the historical heritage in the Royal Palace, feel the tranquility in Wat Unalom, and appreciate the natural scenery in Tonle Sap Lake. Phnom Penh’s living art museum, the Central Market, is also one of the must-visit attractions for tourists. The city's rich culture and natural beauty make it an important destination for travel in Southeast Asia.
