Phnom Penh is the largest city in Cambodia, located at the confluence of the Mekong and the Tonle Sap rivers. In recent years, Phnom Penh has become far more pleasant and has tidied up, though perhaps not "The Paris of the East" pre 1970s, the city's French colonial buildings are beautiful, and its streetscapes make for a pleasant walk especially along Sisowath Quay down by the Tonle Sap River - in many respects the heartbeat of the city.
