The ancient capital of the Khmer Empire was at Angkor, close to present-day Siem Reap. In the fifteenth century, the capital was moved to the area of the intersection of the Sap and Mekong rivers, near present-day Phnom Penh, perhaps to enhance trade. The most densely populated areas now are along the rivers in the provinces near Phnom Penh.
