About Phnom Penh
Phnom Penh, at the confluence of the Mekong and the Tonle Sap Rivers, is the capital of Cambodia and its largest city. Having been liberated in the late 1970s from Khmer Rouge oppression, the city has exploded in activity in the 21st century and now a thumping little metropolis, small at heart but big in vibe. While not yet a rival to Bangkok, it's getting there; get it while it lasts, before it becomes Bangkok.
