Preah Khan of Kompong Svay (Khmer: ប្រាសាទព្រះខ័នកំពង់ស្វាយ), or Prasat Bakan or Bakan Svay Rolay, is an archaeological temple-city complex located 100 km (60 miles) east of Angkor, in Preah Vihear province, Cambodia.
On the road leading from Angkor to Champa, Preah Khan of Kompong Svay was a major centre of Khmer power, particularly in the 12th century CE.
Preah Khan of Kompong Svay is very unusual in that it is oriented to the north-east, breaching the traditional Angkorean east-west alignment, perhaps to point in the direction of Wat Phu, another major Khmer spiritual centre located in present-day Laos.
This temple-city's huge strategic importance was also due to the presence of the Phnom Daek iron deposits, some 30 km (19 miles) to the east. Several iron kilns have been found near Preah Khan of Kompong Svay.
Its isolated location makes it one of the less visited sites in Angkor, but this beautiful place is well worth the trip if you have time.
