Ancient Royal Road

A map and (growing) list of ancient temples, firehouses, hospital chapels and infrastructure along the ancient “Royal Road” network of the Khmer Empire, Cambodia.

The ancient road network of the Khmer Empire was expansive, covering thousands of km’s, centred on Angkor, and headed
– Southeast Royal Road: from Angkor to Kampong Kdei, and southeast to Prasat Andet and Sambor Prei Kuk
– East Royal Road: from Angkor, east to Beng Mealea and Beng Mealea to Preah Khan of Kampong Svay
– Northeast Royal Road: northeast from Beng Mealea to Koh Ker and Wat Phu
– Northwest Royal Road: from Angkor, northwest to Phimai
– Southwest Royal Road: from Angkor, southwest to Sdok Kak Thom.

For our journeys along the ancient road and around Cambodia see Tour journals and the new book, Ancient Cambodia.
