Cambodia's modem-day culture has its roots in the 1st to 6th centuries in a state referred to as Funan, known as the oldest Indianized state in Southeast Asia.
The dominant features of the Cambodian landscape are the large, almost generally located, Tonle Sap (Great Lake) and the Bassac River Systems and the Mekong River, which crosses the country from North to South. Surrounding the Central Plains which covered three quarters of the country’s area are the more densely forested and sparsely populated highlands, comprising: the Elephant Mountains and Cardamom Mountain of the southwest and western regions; the Dangrek Mountains of the North adjoining of the Korat Plateau of Thailand; and Rattanakiri Plateau and Chhlong highlands on the east merging with the Central Highlands of Viet Nam.
The capital city is Phnom Penh.
